Question

For each condition below, state which statistical test you should use. (F-test, T-test, Chi square, Pearson's) 1) You wish to compare the means of two data sets. 2) You wish to compare the standard deviations of two data sets. 3) You wish to compare the distribution of a data set to a hypothesized distribution. 4) You wish to determine whether one variable depends on another variable. State which type of T-test you should use in the following situations. (paired/unpaired, 1 tailed/2 tailed) 1) You have data for heart rate for before and after exercise for 15 people and you propose that exercise increases heart rate. 2) You have data for heart rate after exercise for men and women and you propose that the post-exercise heart rate will be higher for women. 3) You have data for heart rate for before and after exercise for 15 people and you propose that exercise changes heart rate. What statistical test would you use for the following situation? 1) You have data for heart rate after exercise for 20 different exercise durations and you propose that the heart rate will correlate with the duration of the exercise.
