Using question 29, state the value of the test statistic and p-value.

Suppose that in a particular city, it is believed that, historically, the percentage of adults who smoke has been 30%. The health department conducts a survey of 250 randomly selected adult residents of the city. It was found that 55 of the 250 surveyed smoke. Do the data provide evidence that the true percentage of adults in this city who smoke has decreased from the historical value of 30%. Conduct the test at the 0.05 significance level. State the null and alternative statements for this situation.

Using question 13, compute the 95% confidence interval for the unknown population parameter, Write the lower and upper bounds of your confidence interval to one decimal place.

Assume you love to cook in addition to writing well.  Your recipe for tonight includes 4 spices, namely:  cayenne pepper garlic onions oregano You do not have any of these on hand.  On their way home, your roommate could pick up the supplies you need so you write this sentence in an email.  “Please pick up _____(insert the list of spices_____.”   Below, please carefully type into the answer box the list of 4 spices in the order listed above and correctly punctuate that list as it would be in science.

Using question 5, compute the 95% confidence interval for the unknown population parameter, the true mean number of hours worked by U.S. workers. Write the lower and upper bounds of your confidence interval to one decimal place.

Using question 29, state the conclusion (in clear English).

Using question 5, state the conclusion (in clear English).

True or False? Clearly explain your answer.  If we do not reject a null hypothesis at α = 0.01, we also do not reject the null hypothesis at α = 0.05?
