Is a measure of 25 inches "far away" from a mean of
16 inches? As someone with knowledge of statistics, you answer "it depends" and request the standard deviation of the underlying data.
(a) Suppose the data come from a sample whose standard deviation is 3
inches. How many standard deviations is 25
inches from 16 inches?
(b) Is 25 inches far away from a mean of 16 inches?
(c) Suppose the standard deviation of the underlying data is
7 inches. Is 25 inches far away from a mean of
16 inches?

Height data, collected from a statistics class, has a mean
x=68.21 inches, and a standard deviation of s= 4.01 inches. The
sample size of the data was n=36 . Suppose the data collected could
be considered a random sample of UCLA students.
What sample size would be needed for a 90% confidence interval
to have a margin of error,B , within .25?
Give your answer as a whole number.

To estimate the mean height μ of male students on your campus,
you will measure an SRS of students. Heights of people of the same
sex and similar ages are close to Normal. You know from government
data that the standard deviation of the heights of young men is
about 2.8 inches. Suppose that (unknown to you) the mean height of
all male students is 70 inches. (a) If you choose one student at
random, what is the probability that...
