Question: Here are the Degree Reading Power (DRP) scores for a sample of 44 third-grade students

40 26 39 14 42 18 25 43 46 27 19

47 19 26 35 34 15 44 40 38 31 46

52 25 35 35 33 29 34 41 49 28 52

47 35 48 22 33 41 51 27 14 54 45

These students can be considered to be an SRS of the third grades in a suburban school district. DRP scores are approximately normal. Suppose that the standard deviation of scores in this school district is known to be J(standard deviation) =11. The researchers believes that the mean score M of all third graders in this district is higher than the national mean, which is 32.

1. state the appropriate Ho and Ha to test this suspicion.
2. carry out the test. give the P-value and then interpret the results in plain language.
