					Conclusion: Is the claim supported? Why or why not?		Hint: If the p-value is greater than the significance level, we fail to reject the null so there is not enough evidence to reject the hypothesis; we cannot support this claim. If the p-value is less than the significance level, we reject the null hypothesis so we can support this claim.
					If student uses z-test; provide feedback and grade for content.
				Hypothesis Test
				Null Hyp:	m	=	3.5
=				Alt Hyp:	m	>	3.5
≥
≤					significance level =	0.05
≠					test statistic =	1.45407
<					critical value =	1.69913
>					p-value =	0.07833
				Since	0.0783326882	>	0.05	we	fail to reject	the null:	m	=	3.5
