Question

A medical engineer was testing the results on heart pace makers on their accuracy on keeping the heart at the perfect pace of M=60 beats per minute. She wants to test this against the national average, but she cannot obtain the SD from the population and must calculate it from her sample, but will be able to use the mean from her study for the t test calculation. She sampled the heart rates of n=10 patients to compare to the normal average. She wants to make the test strict to make she is not getting a type I error, so sets the alpha level at α=.01. These are the raw numbers of the heart rates that she collected: 62, 63, 65, 59, 64, 65, 67, 60, 62 and 64.
State the hypotheses of the study.
b. Find the critical tvalue for this study
c. Compute the one sample ttest
d. Compute the Cohen's d for the data
e. State the results in APA format (numbers and words) and don’t forget to include all parts in the sentence and the direction of the results.
