Question

Questions 5-7 are related to the following information
In the population of employees in your company, 30 percent contribute to the annual United Way campaign. You plan to take a sample of size n = 200 and calculate the sample proportion who contribute to United Way.
5	In random samples of size n = , the expected value of the sample proportion is ______.
a	0.35
b	0.32
c	0.30
d	0.021

6	In the previous question, the standard error of the sample proportion is:
a	0.0560
b	0.0467
c	0.0402
d	0.0324

7	95% percent of sample proportions from samples of size n = 200 deviate from the population proportion of π = 0.30 by no more that ±____ (or ____ percentage points).

a	0.033	(3.3 percentage points.)
b	0.041	(4.1 percentage points.)
c	0.051	(5.1 percentage points.)
d	0.064	(6.4 percentage points.)
