Use the sample data to test the claim that the population mean is less than 1.0 mg. Does the conclusion apply to the mean nicotine level of all 100 mm cigarettes (not menthol or light) smoked by consumers? Why or why not? Use a significance level of 0.05.

Explanation / Answer
Data:
n = 29
= 1
s = 0.313
x-bar = 0.941
Hypotheses:
Ho: 1
Ha: < 1
Decision Rule:
= 0.05
Degrees of freedom = 29 - 1 = 28
Critical t- score = -1.701130908
Reject Ho if t < -1.701130908
Test Statistic:
SE = s/n = 0.313/29 = 0.058122641
t = (x-bar - )/SE = (0.941 - 1)/0.0581226408494172 = -1.015094964
p- value = 0.15937615
Decision (in terms of the hypotheses):
Since -1.015094964 > -1.701130908 we fail to reject Ho
Conclusion (in terms of the problem):
There is no sufficient evidence that < 1 mg
Yes the conclusion applies to the mean nicotine level of all 100 mm cigarettes (not menthol or light) smoked by consumers.
