Suppose that a student is working on a statistics project using data on pulse rates collected from a random sample of students from her college. From her sample, she finds the 95% confidence interval is (70.48, 79.52). Give your answers to 2 decimal places.
What is the average pulse rate for this sample of students?
What is the standard error for this statistic?
Which of the two following histograms most accurately represents the sampling distribution for this average?
Histogram B
Select each correct interpretation of the confidence interval in the prompt
A. If the sampling were repeated many times, you would expect that 95% of the resulting confidence intervals to contain the average pulse rate of all students at her college.
B. She is 95% confident that the average pulse rate of students in the sample is between 70.48 and 79.52.
C. She is 95% confident that the average pulse rate for all US college students is between 70.48 and 79.52.
D. If the sampling were repeated many times, you would expect 95% of the resulting samples to have a sample average that falls in the interval from 70.48 to 79.52.
E. 95% of the time, all students at her college will have a pulse rate between 70.48 and 79.52.
F. 95% of all students at her college have a pulse rate 70.48 to 79.52, and the rest have higher or lower pulse rates.
G. She is 95% confident that the average pulse rate for all students at her college is between 70.48 and 79.52.
H. None of the above
