To this point, the work of days missed per month by workers at a large corporation has average 2.25. A new flexible workday arrangement has been introduced and it is hoped that by introducing this "flex time" that the average workdays miss per month will be reduced. Let alpha=.05 A) defined the appropriate parameter for this problem and then set up the appropriate Null and alternative hypothesis a. The average number of work days missed by all workers at a large corporation. Ho: x bar=2.25; Ha: x bar < 2.25 b. The average number of work days missed by all workers at a large corporation Ho: mu = 2.25; Ha: mu < 2.25 c. The number of work days missed by the workers d. The average number of workdays mess by the 20 workers at a large corporation. Ho: mu =2.25; Ha: mu. 2.25
