Explain the relationship between confidence intervals and hypothesis tests using the answers to questions 21 and 22. Be sure to explain how you can tell the outcome of the hypothesis test by looking at the confidence interval. (Hint: compare H 0 to the confidence interval). 95% CI for the population mean heart rate: 70.39 to 72.44 beats per minute. Interpretation: 21) Based on this sample of 496 students, we are 95% confident that the true mean resting heart rate of UK students lies between about 70.4 and 72.4 bpm. Equivalently, in repeated samples, 95% of such intervals would contain the true mean. 22) Here is what the SPSS output shows for the one-sample t test with test value 80 bpm. Hypotheses; Null (H0): = 80 bpm Alternative (H1): 80 bpm Sample mean: 71.41 bpm Sample SD: 11.619 bpm Standard error of the mean: 0.522 bpm t value: -16.458 (df = 495) p-value (Sig. 2-tailed):
