Jody obtained the following random sample of number of books read in the last year:

3          1          6          1          1

2          2          12       9          5

3          0          2          2          4

Jody hypothesized that the average number of books read is 2.5.

Jody's hypotheses are:

H0 : µ ≥ 2.5

HA : µ <2.5

Please calculate 1) null and alternative hypothesis 2) alpha value 3) p-value 4) conclusion 5) If Jody rejected the null hypothesis wrongly, what type of error did she make, a Type I or a Type II?
