A note on estimation of population mean in sample survey using auxiliary info...Alexander Decker
1. The document proposes a class of estimators for estimating the population mean in two-phase sampling using auxiliary information.
2. Some common estimators like the ratio, product, and regression estimators are special cases within the proposed class. Expressions for bias and mean squared error of the estimators are obtained up to the first order of approximation.
3. Asymptotically optimum estimators are identified that have minimum mean squared error. The proposed class of estimators is found to perform better than usual ratio and other estimators for population mean estimation.

It is accompanied by an introduction from three physics panel members wishing students the best on their upcoming exam and emphasizing the importance of working together to succeed.
1. The document discusses using scatterplots to analyze bivariate data and examine relationships between two variables. It provides an example of data collected on depth of snow and number of skiers at a ski resort over 12 weekends.
2. A scatterplot is created with depth of snow on the x-axis and number of skiers on the y-axis. This shows a general upward trend, indicating higher skier numbers with more snow.
3. The document discusses key aspects of scatterplots, including identifying independent and dependent variables and exploring linear and non-linear relationships between variable pairs. Examples are provided to illustrate these concepts.
This document discusses correlation and regression analysis. It begins by defining bivariate distribution as a distribution where each data point consists of values for two variables. Correlation analysis studies the relationship between two variables. Positive correlation means the variables increase or decrease together, while negative correlation means they change in opposite directions. Linear correlation means a constant change in one variable corresponds to a change in the other, while non-linear correlation means the relationship is not constant. The coefficient of correlation r measures the strength of the linear relationship between -1 and 1. Rank correlation uses the ranks of data values rather than the actual values.

Strategies for Effective Upskilling is a presentation by Chinwendu Peace in a Your Skill Boost Masterclass organisation by the Excellence Foundation for South Sudan on 08th and 09th June 2024 from 1 PM to 3 PM on each day.
This slide is special for master students (MIBS & MIFB) in UUM. Also useful for readers who are interested in the topic of contemporary Islamic banking.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

An import error occurs when a program fails to import a module or library, disrupting its execution. In languages like Python, this issue arises when the specified module cannot be found or accessed, hindering the program's functionality. Resolving import errors is crucial for maintaining smooth software operation and uninterrupted development processes.

(c) 1. Rod A and rod B floats in water because their weights
are equal to buoyant force. // their densities are less
than water.
2. Rod B has greater mass/weight and density compared
to Rod A.
3. Hence buoyant force/ weight of water displaced of
rod B is greater than rod A.
4. Since the cross section of both rods are equal, rod B
floats lower than rod A.
