Question

(a) What is the probability that a person who was polled prefers chocolate ice cream to vanilla? Round your answer to four decimal places.

Answer 1

`P(k)=0.2628`

Explanation:

Given

`n = 1693` --- sample size

`k = 445` --- those that prefer chocolate ice cream to vanilla

Required

`P(k)`

This is calculated as:

`P(k)=(k)/(n)` --- probability formula

So, we have:

`P(k)=(445)/(1693)`

`P(k)=0.2628`
