Reading Program Summer reading programs are very popular with children. At the Citizens Library, Team Ramona read an average of 23.2 books with a standard deviation of 5.1. There were 16 members on this team. Team Beezus read an average of 26.1 books with a standard deviation of 2.8. There were 19  members on this team. Did the variances of the two teams differ? Use =α0.10. Use the traditional method of hypothesis testing and let σ1be the standard deviation for Team Ramona. Assume that all variables are normally distributed.

State the hypotheses and identify the claim.

H0:  Claim or not a claim

H1:  Claim or not a claim

This Hypothesis test is a one-tailed or two-tailed test?

Find the Critical Value:  Round to at least two decimal places.

Compute the test Value: 

Make the decision to reject or accept the null hypothesis.

Summarize the results. Is there enough evidence to support the claim.
