Chapter 6, Problem 6.15P

Two individuals are running for mayor of your town. You conduct an election survey a week before the election and find that 51% of the respondents prefer candidate A. Can you predict a winner? Use the 99% level. (HINT: In a two-candidate race, what percentage of the vote would the winner need? Does the confidence interval indicate that candidate A has a sure margin of victory? Remember that while the population parameter is probably [ α = 0.01 ]in the confidence interval, it may be anywhere in the interval.)

P s = 0.51 N = 578

In exploring possible sites for a convenience store in a large neighbourhood, the retail chain wants to know the proportion of ratepayers in favour of the proposal. If the estimate is required to be within 0.1 of the true proportion, would a random sample of size n = 100 from the council records be sufficient for a 95% confidence interval of this precision?
An apple farmer inspects a large random sample of his apples and finds that 20% contain excellent worms. He wants to charge his customers extra, and claims that the 90% confidence interval for the population pro- portion of apples that contain worms has a margin of error of at most 0.01. At least how many apples did the farmer inspect?
A 30 month study is conducted to determine the difference in rates of accidents per month between two departments in an assembly plant. If a sample of 12 from the first department averaged 12.3 accidents per month with a standard deviation of 3.5, and a sample of 9 from the second department averaged 7.6 accidents per month with standard deviation of 3.4, find: The t-value for a 95% confidence interval is:   A. 2.09302 B. 1.724718 C. 2.08596 D. 1.729133 E. none of the preceding
