27) A company manager wishes to test a union leader's claim that
absences occur on the different week days with the same
frequencies. Use a significance level of 0.01 to test the manager's

on a Tuesday, 38 occurred on a Wednesday, 33 occurred on a
Thursday, and 12 occurred on a Friday. Use the p-value method of
hypothesis testing.

1. A manager wants to test if there is a significant difference
in the variance of the output from two similar machines. It has
been determined that the output of the two machines is normally
distributed. To carry out the hypothesis test about the population
variances, the manager takes random samples from the output of each
machine. The results are: Machine 1 Machine 2 1x=128.9 2x=159.5 s1=
6.8 s2= 7.2 n1=13 n2=15 a.)What is the observed value of the
