Question
Use the t-distribution and the sample results to complete the test of the hypotheses.
Use a 5% significance level. Assume the results come from a random sample, and if the
sample size is small, assume the underlying distribution is relatively normal.
Test Ho: u=109.2 vs H,: u<109.2using the sample results x= 105.1, s = 15.5,
with n=100.
A The p-value is 0.452. The p-value is larger than any reasonable significance level, so we find
enough evidence to support the alternative hypothesis.
B The p-value is 0.096. The p-value is larger than the significance level of 0.05, so we do not
reject the null hypothesis and do not find sufficient evidence to support the alternative.
C The p-value is 0.0048. The p-value is very small, and below any reasonable significance
level. There is no evidence to support the alternative hypothesis.
DThe p-value is 0.096. The p-value is larger than the significance level of 0.05, so we rejeet
the null hypothesis and find sufficient evidence to support the alternative.
E The p-value is 0.0048. The p-value is very small, and below any reasonable significance
level. There is strong evidence to support the alternative hypothesis.
