PEER’S RESPONSE:

A. A local preschool is divided into two grades, Pre-K3 and Pre-K4. The teachers of the preschool want to know how many times a week each grade buys school lunch so they can plan their budget and buy food supplies. At the end of the month, the teachers gather the data for many times each grade buys school lunch. 

B. My decision was to fail to reject the null hypothesis since the critical value (2.043) was bigger than the obtained value (0.71).

C. Yes, it would have changed because the one tailed and two tailed charts are completely different and the critical value would have been a different number to compare to the obtained value.
