The document compares two normal distributions, labeled A and B, noting that distribution A has a lower mean and B has a higher mean. Additionally, it highlights that distribution A has a smaller standard deviation compared to B, indicating a tighter clustering of values. The differences in mean and standard deviation are visually represented in the accompanying figure.

1. The figure below shows two normal distributions. A and B. The distribution that has the higher
mean is A B The distribution that has the higher standard deviation is A B
Solution
a) B
b) A
Mean : mean lis in the middle most observation, The chart A clearly visible that it has lessar
mean than B
Standard deviation: It is the value distance from the mean, Figure A has longer distance b/w the
edges to middle
