Question

A courier service company wishes to estimate the proportion of
people in various states that will use its services. Suppose the
**true proportion is 0.06**. If **228**
are sampled, what is the probability that the sample proportion
will differ from the population proportion by **less than
0.03**? Round your answer to four decimal places.

Answer #1

Solution

Given that,

= [p ( 1 - p ) / n] = [(0.06 * 0.94) / 228 ] = 0.0157

= P[(-0.03) / 0.0157 < ( - ) / < (0.03) / 0.0157]

= P(-1.91 < z < 1.91)

= P(z < 1.91) - P(z < -1.91)

= 0.9719 - 0.0281

= 0.9438

Probability = **0.9438**
