A confidence interval, at the 95% confidence level, will be used
to answer the question, "What is the mean annual salary (in US
dollars) of a Tesla car owner?" Data was collected from
36 Tesla owners across the US. The mean annual salary of those 36
Tesla owners was $254000. The standard deviation of ALL
Tesla owners is known to be $1057.

At a confidence level of 95% a confidence interval for a
population proportion is determined to be 0.65 to 0.75. If the
sample size had been larger and the estimate of the population
proportion the same, this 95% confidence interval estimate as
compared to the first interval estimate would be
A. the same
B. narrower
C. wider
How is the rejection region defined, and how is that related to
the p value? When do you reject or fail to reject the null
hypothesis? Why do you think statisticians are asked to complete
hypothesis testing? Can you think of examples in courts, in
medicine, or in your area?
