Based on the information provided, I would not convict Adams. While the DNA evidence places him in a very small group of potential suspects, there are reasonable doubts raised by the defense arguments regarding the accuracy of the victim's identification and Adams' alibi. Statistical evidence alone is not enough to determine guilt beyond a reasonable doubt in this case.

Read the Syllabus and FAQ on how to do your homework before beginning the assignment!
To get consideration for full credit, you must:
· Follow directions;
· Show all work required to arrive at answer (statistical calculations often require multiple steps, so you need to write these down, not just skip to the final answer)
· Use appropriate statistical notation at all times (e.g. if you are calculating a population mean, begin with the equation for population mean)
· Use units in your answer, where appropriate (e.g. a mean time would be “6.5 hours” rather than just “6.5”)

The fundamental problem of Forensic StatisticsGiulia Cereda
When using Y-chromosome DNA profiles, it often happens that a DNA profile found on a crime scene and matching the suspect’s profile does not appear in the relevant data-base. This creates a big challenge to the analyst who is required to supply a likelihood ratio (LR) or match-probability in order to quantify the evidential value of the match. Sensible estimation of the LR seems to rely on sensible estimation of the population frequency of this previously unseen haplotype.
There are three existing proposals of quite different nature: Roewer et al. (2000), based on Bayesian estimation of the haplotype frequency with a Beta prior; Brenner (2010), based on the number of singletons observed in the database; and Andersen et al. (2013) using a mixture of independent discrete Laplace distributions as a parametric approximation of the distribution of allelic frequencies.
We add two new methods. One is similar to Brenner’s, and like Brenner’s is strongly related to the Good-Turing estimator. A second method is based on Anevski, Gill and Zohren’s (arXiv.org/math.ST:1312.1200) study of a non-parametric maximum-likelihood estimator. It is somehow intermediate between the parametric approach of Andersen and non-parametric methods based on Good-Turing estimators. We believe that it avoids the disadvantages of those while moreover providing a supplementary means of evaluating their accuracy.
For all methods it is imperative to assess two more levels of uncertainty, beyond the uncertainty about which hypothesis is true given the evidence, which would hold if we knew everything about the population probability distribution. LR is a ratio of probabilities which are usually based on a model which is at best only a good approximation to the truth. Moreover we only estimate parameters of that model by fitting it to the data in our database.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

STATISTICS
1.
2. A type of mathematical analysis
involving the use of quantified
representations, models and
summaries for a given set of empirical
data or real world observations.
Statistical analysis involves the process
of collecting and analyzing data and then
summarizing the data into a numerical
form.
3. Statistics is a general term used to summarize a
process that an analyst, mathematician or
statistician can use to characterize a data set. If
the data set is based on a sample of a larger
population, then the analyst can extend
inferences onto the population based on the
statistical results from the sample.
Some statistical measures include regression
analysis, mean, kurtosis, skewness, analysis of
variance and variance.
4. Gottfried Achenwall used the word statistik at a German University in 1749 which
means that political science of different countries. In 1771 W. Hooper
(Englishman) usedthe word statistics in his translation of Elements of Universal
Erudition written by Baron B.F Bieford, in his book statistics has been defined as
the science that teaches us what is the political arrangement of all the modern
states of the known world. There is a big gap between the old statistics and the
modern statistics, but old statistics also used as a part of the present statistics.
During the 18th century the English writer have used the word statistics in their
works, so statistics has developed gradually during last few centuries. A lot of work
has been done in the end of the nineteenth century.
At the beginning of the 20th century, William S Gosset was developed the
methods for decision making based on small set of data. During the 20th century
several statistician are active in developing new methods, theories and application
of statistics. Now these days the availability of electronics computers is certainly a
major factor in the modern development of statistics.
5. Types of Data:
Attribute:
Discrete data. Data values can only be integers. Counted data or
attribute data. Examples include:
How many of the products are defective?
How often are the machines repaired?
How many people are absent each day?
Variable:
Continuous data. Data values can be any real number.
Measured data.
Examples include:
How long is each item?
How long did it take to complete the task?
What is the weight of the product?
Length, volume, time
6. MEAN MEDIAN MODE

8. Grouped frequency distributions
Can be used when the range of values
in the data set is very large. The data
must be grouped into classes that are
more than one unit in width.
Examples - the life of boat batteries in
hours.
9. Ungrouped frequency distributions
Ungrouped frequency distributions - can be used
for data that can be enumerated and when the
range of values in the data set is not large.
Examples - number of miles your instructors

15. LEGAL
You have just been selected for jury duty. In 1996 in
England, Denis Adams was suspect in a rape trial.
Listen closely to the details of the case and the
arguments presented before deciding your verdict.
(We have simplified the actual case/arguments for the
purpose of this illustration.)
15
16. LEGAL
Prosecution Argument
• Adams’ DNA profile matches that of evidence found
at the scene of the crime
•If Adams is innocent, there is only a 1 in 20 million
chance that his DNA would match that found at the
crime
• Therefore, the probability Adams is innocent is only
.00000005, hence the probability he is guilty is 1
minus that, .9999995. Thus Adams is guilty beyond
the shadow of a doubt.
16
17. LEGAL
Defense Argument
• If the odds of a DNA match for any person is
1/ 20,000,000, since there are 60 million people in
England, there are on average 3 other people with this
DNA type (in 1996).
•Since it is equally likely to be any of these others, the
probability of Adams’ guilt is 1/3 = .33, which is not
enough certainty to convict.
17
18. LEGAL
Defense Argument
• In an identity line up, victim failed to pick out Adams
• Victim describes an attacker in his 20’s
• Adams is 37
• Victim guessed Adams to be about 40
• Adams had an alibi for the night of the crime (he
spent the night with his girlfriend)
