You may need to use the appropriate appendix table or technology to answer this question. The proportion of individuals insured by the All-Driver Automobile Insurance Company who received at least one traffic ticket during a five-year period is 0.15. (a) Show the sampling distribution of p if a random sample of 180 insured individuals is used to estimate the proportion having

Suppose the true proportion of voters in the county who support a school levy is 0.53. Consider the sampling distribution for the proportion of supporters with sample size n = 101.What is the mean of this distribution? What is the standard error of this distribution?

Suppose the true proportion of voters in the county who support a specific candidate is 0.52. Consider the sampling distribution for the proportion of supporters with sample size n = 142.What is the mean of this distribution? What is the standard error of this distribution?

About 71% of all female heart transplant patients will survive for at least 3 years. Eighty female heart transplant patients are randomly selected. What is the probability that the sample proportion surviving for at least 3 years will be pq less than 63%? Assume the sampling distribution of sample proportions is a normal distribution. The mean of the sample proportion is equal to the population proportion and the standard deviation is equal to The probability that the sample proportion surviving for at least 3 years will be less than 63% is (Round to four decimal places as needed.)

Suppose that the efficacy of a certain drug is 0.56. Consider the sampling distribution (sample size �=99) for the proportion of patients cured by this drug. What is the mean of this distribution?  What is the standard error of this distribution? Round the answer to three decimal places.

About 77% of all female heart transplant patients will survive for at least 3 years. Eighty female heart transplant patients are randomly selected. What is the probability that the sample proportion surviving for at least 3 years will be less than 69%? Assume the sampling distribution of sample proportions is a normal distribution. The mean of the sample proportion is equal to the population proportion and the standard deviation is equal to The probability that the sample proportion surviving for at least 3 years will be less than 69% is (Round to four decimal places as needed.)

As the sample size (n) increases, does the sampling distribution of the sample mean stay the same, look more and more like a uniform distribution, or become more tightly clustered around the population mean?

Suppose that the efficacy of a certain drug is 0.52. Consider the sampling distribution (sample size n = 100) for the proportion of patients cured by this drug. What is the mean of this distribution? What is the standard error of this distribution?
