1). Standard deviation is 2, coefficient of variation is 70%, find the mean.

2). The following observations are given: 3,5,8,7,1. find the standard deviation.

3). Mean is 20, standard deviation is 5. How many standard deviations is 15 away
from the mean?

4). A and B are independent, probability of A is .45 and probability of B is .25 then
what is the probability of A given B?

5). If probability of A is .15 and probability of B is .4, then what is probability of A
and B (Union)? What is the probability of A intersect B if they are not mutually exclusive? What is
the conditional probability of A given B?

There are 2 classes. Afternoon class with mean = 70 and standard deviation is 15 Morning class with a mean = 70 and standard deviation of 5. The spread of grades in the morning class has less variation and located mostly around the mean.   According to emperical rule (assuming grades are normally distributed) it says, 68% of grades are falls within 1 standard deviation, 95% of grades falls within 2 standard deviation and 99.7% of grades falls within 3 standard...

A population has mean 72 and standard deviation 6. Find the mean and standard deviation of X for samples of size 45. Find the probability that the mean of a sample of size 45 will differ from the population mean 72 by at least 2 units, that is, is either less than 70 or more than 74. (Hint: One way to solve the problem is to first find the probability of the complementary event.)
