The mean number of sick days an employee takes per year is believed to be about ten. Members of a personnel department do not believe this figure. They randomly survey eight employees. The number of sick days they took for the past year are as follows: 12; 4; 15; 3; 11; 8; 0; 8. Let x = the number of sick days they took for the past year. Should the personnel team believe that the mean number is ten? Alpha = 0.05 Ho u = 10, H 4: 10 -z=-1.12 At the 5% significance level, there is insufficient evidence to conclude that the mean number of sick days is not ten 95% CI is (4.9443. 11.806) p-value
