A large study was done to compare two treatments for recurring ear infections in young children. A total of 150 subjects were recruited for the study, with 50 subjects assigned at random to Treatment 1 and the remainder to Treatment 2. As part of the study, various types of demographic information were gathered. The following table classifies the mother's education level into one of four categories for each of the treatment groups.

Not HS grad HS grad Some college College grad
Treatment 1 10 22 12 6
Treatment 2 23 55 8 14

A. The null hypothesis is that the distribution of mother's educational level is the same for both treatment groups. The value of the chi-square statistic is 7.422. The P-value is:

-less than 0.05.

-between 0.05 and 0.10.

-greater than 0.10.

B. Under the null hypothesis that the distribution of mother's educational level is the same for both treatment groups, the expected number of mothers who are college grads for Treatment 2 is...?
