If you were to construct a 99% confidence interval for the true proportion of all adult Johnson City residents that favor banning smoking in restaurants, how would this interval compare to the 95% interval you computed in question 4, if p-hat and n remained the same?Question 5 options:

The 99% confidence interval would be wider; that is, it would have a larger margin of error.

The 99% confidence interval would be narrower; that is, it would have a smaller margin of error.

There would be no change between the two intervals by increasing the confidence level from 95% to 99%.

SaveQuestion 6(1 point) From time to time police set up roadblocks to check cars to see if the safety inspection is up to date. At one such roadblock they issued tickets for expired inspection stickers to 22 of 628 cars they stopped. Based on the results at this roadblock, they construct a 95% confidence interval for the true proportion of all drivers with expired inspections and find it to be (2%, 5%). Intepret this interval.Question 6 options:

95% of the cars stopped have between 2% and 5% expired safety inspection stickers.

We are 95% confident that the true proportion of all automobiles in the region whose safety inspections have expired lies somewhere between 2% and 5%.

SaveQuestion 10(1 point) What conclusion would you make for this test if alpha = 0.05?Question 10 options:

Since the p-value is less than alpha, we would decide to reject the null hypothesis, indicating evidence that the true proportion of seniors that think their job propsects are "Good" is more than 50%.

Since the p-value is greater than alpha, we would decide to fail to reject the null hypothesis, indicating evidence that the true proportion of seniors that think their job propsects are "Good" equals 50%.
