Suppose that 70% of all college women have been on a diet within the past 12 months. A sample survey will interview an SRS
of 267 college women. Let p be the proportion of women in the sample who have been on a diet within the past 12 months.
(a) Describe the shape, center, and variability of the sampling distribution of p.
Shape:
Approximately normal
because np =
186.9
and n(1 - p) =
80.1
are
both at least 10
Center: μp
Variability: σp
0.70
0.028
(b) Find the probability that 75% or more of the women in a random sample of size 267 have been on a diet.
Round your answer to 4 decimal places.
