Daniel believes that people perform better in the barbell curl, on average, if they are encouraged by a coach. Be recruited 29 subjects to participate in an experiment and randomly assigned them into two groups. Daniel gave one group verbal encouragement during the exercise and was quiet during the exercise for the other group. He recorded the total number of barbell curls each subject was able to complete before setting the bar down.
a. Explain the purpose of random assignment in this experiment. Here are boxplots that summarize the distribution of a number of barbell curls for each group.
b. Compare these distributions
c. State the hypotheses Daniel should use to test his belief about receiving encouragement during exercise. Make sure to define any parameters you use.
d. Identify the significance test Daniel should use to analyze the results of his experiment and show that the conditions for this test are met.
e. The P-value for Daniel's test is 0.107. What conclusion should Daniel make at the a=0.05 significance level?
