The manager of a paint supply store wants to estimate the actual amount of paint contained in 1-gallon cans purchased from a nationally known manufacturer. the manufacturer's specifications state that the standard deviation of the amount of paint is equal to 0.02 gallon. a random sample of 50 cans is selected, and the sample mean amount of paint per 1-gallon can is 0.998 gallon. complete parts (a) through (d).

a. construct a 95% confidence interval estimate for the population mean amount of paint included in a 1-gallon can.

b. on the basis of these results, do you think the manager has a right to complain to the manufacturer? why?

a 1-gallon paint can containing exactly 1-gallon of paint lies 95% confidence interval.

c. must you assume that the population amount of paint per can is normally distributed here? explain.

d. construct a 90% confidence interval estimate. how does this change your answer to part (b)?

how does this change your answer to part (b)?

a 1-gallon paint can containing exactly 1-gallon of paint lies 90% confidence interval. the manager right to complain to the manufacturer.

In a sample of 2023 u.s. adults, 373 said franklin roosevelt was the best president since world war ii. two u.s. adults are selected at random from the population of all u.s. adults without replacement. assuming the sample is representative of all u.s. adults, complete parts (a) through (d). (a) find the probability that both adults say franklin roosevelt was the best president since world war ii. the probability that both adults say franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (b) find the probability that neither adult says franklin roosevelt was the best president since world war ii. the probability that neither adult says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (c) find the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii. the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (d) which of the events can be considered unusual? explain. select all that apply. the event in part left parenthesis a right parenthesis is unusual because its probability is less than or equal to 0.05. the event in part (b) is unusual because its probability is less than or equal to 0.05. none of these events are unusual. the event in part (c) is unusual because its probability is less than or equal to 0.05.
