air from lungs. Patients with asthma or other respiratory conditions often have restricted PEF. The mean PEF for children free of asthma is 306. An investigator wants to test whether children with chronic bronchitis have restricted PEF. A sample of 40 children with chronic bronchitis are studied and their mean PEF is 279 with a standard deviation of 72. Alpha = 0.05

Question

Help!Which of the following is true?a. If a 90% CI for the mean is (75.3 to 80.9), we would reject

H0: Mean=70 in favor of H1: Mean not equal 70 at alpha = 0.05.

b. If a test is run and p=0.0356, then we can reject H0 at alpha = 0.01

c. If a 95% CI for the difference in two independent means is (-4.5 to 2.1), then the point estimate is -2.1

d. If a 95% CI for the difference in two independent means in (2.1 to 4.5), there is no significant difference in means

e. The margin of error is always greater than or equal to the standard error.
