Answer:
And the p value calculated for the right tailed ted is:
The significance level provided for this case is 5% or . We can see that the p value is lower than this significance level so then we have enough evidence to reject the null hypothesis in favor to the alternative hypothesis and we can conclude that the true parameter of interest for this case is significantly higher than 16. If we find a confidence interval at the same significance level we should get the same results.
Explanation:
for this case she want to test the following system of hypothesis.
Null hypothesis:
Alternative hypothesis:
And the statistic for this case is given by:
