The mean score on a certain achievement test at the turn of the century was 75.However, national standards have been implemented which may lead to a change in the mean score.A random sample of 36 scores on this exam taken this year yielded the following data set. At a 10% significance level, test the claim that the mean of all current test scores is not the same as in 2000.

85	77	74	88	89	66	0	70	80
58	76	86	89	73	82	72	0	75
82	82	80	76	87	76	77	67	68
72	49	73	75	82	18	81	30	65

a.	Give the null and alternative hypotheses for this test in symbolic form.
H0:
H1:

b.	Determine the value of the test statistic.

c.	Determine the appropriate critical value(s).

d	Detemine the P-value.

e.	Is there sufficient evidence to support the claim that the mean achievement score is now different than 75? Explain your reasoning.
