Warranty records show that the probability that a new car needs a warranty repair in the first 90 days is 0.05.  If a sample of 3 new cars is selected: The key components of this problem are:Sample size (trials) = 3 new carsProbability of “success” = 5% 1. Number of “successes”: A: Exactly 0B: 1 or moreC: More than one   Question one please, answer to select from is below the question.

Q5: Assume that 75% of all employees at York University are in favor of unionization. A sample of 50 York employees were taken. a. Show the sampling distribution of the proportion of the employees at York University are in favor of unionization. b. What is the probability that the sample proportion will be within ±0.03 of the population proportion?

Thirty-three percent of all Americans drink bottled water more than once a week (Natural resources Defense Council, December 4, 2015). Suppose you have been hired by the Natural Resources Defence Council to investigate bottled water consumption in St. Paul. You plan to select a sample of St. Paulites to estimate the proportion who drink bottled water more than once a week. Assume the population proportion of St. Paulites who drink bottled water more than once a week is 0.33, the same as the overall proportion of Americans who drink bottled water more than once a week. Use z-table. a. Suppose you select a sample of 540 St. Paulites. Show the sampling distribution of P (to 4 decimals). E(P) .33 Op = .0202 b. Based upon a sample of 540 St. Paulites, what is the probability that the sample proportion will be within 0.07 of the population proportion (to 4 decimals). probability 0.9994 c. Suppose you select a sample of 280 St.Paulites. Show the sampling distribution of (to 4 decimals). E(P)…
