1.A major corporation in Chicago noticed that last year employee's averaged p = 5.8 sick days during the winter season. To try and reduce absences, the company offered free u shots this year. For a sample of n = 30 people who took the shots, the average number of absences was M : 3.6 with a Sum of Squares (88) = 396. Did the administration of flu shots significantly reduce absenteeism? a. State the null & alternative hypotheses. b. Indicate the df, the alpha, and the t critical value. c. Calculate your t-statistic (include the standard deviation, standard error and t-value). d. Interpret the findings (include your decision regarding the null hypothesis and a description of the pattern of results with supporting statistics in APA style). 6. Calculate the Cohen's d and r2 value. Indicate the size of the Cohen's d and describe how much variance in absenteeism can be accounted for by whether employees take the flu shot
