Question

Thirty-two percent of primary care doctors think their patients receive unnecessary medical care. If required, round your answer to four decimal places.

(a)

Suppose a sample of 300 primary care doctors was taken. Show the distribution of the sample proportion of doctors who think their patients receive unnecessary medical care.

	np =
	n(1-p) =

E(p) =
σ(p) =

(b)

Suppose a sample of 500 primary care doctors was taken. Show the distribution of the sample proportion of doctors who think their patients receive unnecessary medical care.

	np =
	n(1-p) =

E(p) =
σ(p) =

(c)

Suppose a sample of 1,000 primary care doctors was taken. Show the distribution of the sample proportion of doctors who think their patients receive unnecessary medical care.

	np =
	n(1-p) =

E(p) =
σ(p) =

(d)

In which of the preceding three cases, part (a) or part (b) or part (c), is the standard error of p smallest? Why?

The standard error is the smallest in - Select your answer -part (a)part (b)part (c)Item 13 because p is - Select your answer -the samenot the sameItem 14 in parts (a), (b), and (c) and the sample size is largest in - Select your answer -part (a)part (b)part (c)Item 15 .
