The Personnel Manager of a large corporation believes that regular physical exercise leads to a lower resting pulse rate (and so healthier staff). Data was collected on resting pulse rate and whether or not people exercised regularly for a random sample of 22 employees of the corporation. The results are given below. Exercise regularly Do not exercise regularly 72 62 72 60 63 75 64 60 52 64 80 68 64 84 66 72 62 84 76 60 78 84 (a) Formulate appropriate hypotheses to test if the average resting pulse rate is lower in employees who regularly exercise compared with those who do not. (b) Perform a parametric test of the above hypotheses and draw conclusions based on the P-value of the test. (c) Perform a non-parametric test to analyze the same data. (d) State all underlying assumptions for the tests in parts (b) and (e) and comment on the similarities/differences in the outcomes of the tests.

Geographer Lalli is interested in investigating whether there is a difference in average humidity in four different types of soil. To test this hypothesis, he took 10 samples for each type of soil and measured the humidity. Lalli is slippery in statistics and he decided to perform a variance analysis to analyze the data. He had started filling out a variance analysis table but could not complete it. Fervic sum Degrees Among square sums Between groups 93,85 xx xx Within groups xx xx xx Whole 290,67 xx a) Finish filling in the fields that Lalli did not manage to fill in (marked xx)b) Carry out an appropriate hypothesis test to verify Lalla's hypothesis. What conclusion can he draw (use α = 0.05)? Show all six steps.

The club owner was wondering whether all three comedians (enumerated COMEDIAN 1, 2, and 3) generated the same average ticket (TICKETSOLD) and beverage (BEVSOLD) sales. What do you tell them? You need to figure out the answer to the above question via: Perform the Shapiro-Wilk test of normality and Levene’s (equality of variances) test for TICKETSOLD and BEVSOLD. Write up all tests. Given what you figured out in part (a), which variable(s) may be used in an ANOVA? How do you know? Perform the ANOVA with Tukey HSD post hoc test for variables suitable for an ANOVA. Write up the results. Create a 3-5 sentence response answering the owner’s question. Make sure you integrate the findings from parts (a)-(c) in your response. You may assume the owner possesses a knowledge of statistics equal to your own. The ANOVA Procedure Dependent Variable: VARIABLE Source DF Sum of Squares Mean Square F Value Pr > F Model df…
