About 80% of all female heart transplant patients will survive for at least 3 years. Seventy 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 76%? 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 pq/n. The probability that the sample proportion surviving for at least 3 years will be less than 76% is . (Round to four decimal)

The average income in a certain region in 2013 was $78,000 per person per year. Suppose th standard deviation is $33,000 and the distribution is right-skewed. Suppose we take a random sample of 100 residents of the region. a. Is the sample size large enough to use the Central Limit Theorem for means? Explain. b. What are the mean and standard error of the sampling distribution? c. What is the probability that the sample mean will be more than $3,300 away from the population mean? a. Choose the correct answer below. A. Yes, it is large enough because the sample size of 100 is greater than 25. B. No, it is not large enough because the sample size of 100 is not greater than 10% of the population. OC. Yes, it is large enough because the population standard deviation of 33,000 is larger tha the sample size of 100. OD. No, it is not large enough because the sample size of 100 is less than 250. b. The mean is $ and the standard error is $ (Type integers or decimals. Do not round.) c. The…

Suppose you are playing a game and you get to roll 40 six-sided dice on your next turn. If you get a total of 160 or more from the 40 dice, you will win the game. Using sampling distributions, what is the probability that you will get a total of 160 or more with the 40 dice? Some useful things to know: When one six-sided die is rolled, the die roll (or number of spots showing) has a mean of 3.5 and a standard deviation of approximately 1.71.
