Question

A survey of 2690 musicians showed that 368 of them are left-handed. Find a point estimate for p, the population proportion of musicians that are left-handed.

Answer 1

Answer: 0.137.

Explanation:

Let p be the population proportion of musicians that are left-handed.

Given: Sample size : n= 2690 [subset of population]

Number of musicians that are left-handed: x= 368

Then the sample proportion:
`\hat{p}=(368)/(2690)\approx0.137`

Since sample proportion is the best point estimate of the population proportion.

Hence, a point estimate for p, the population proportion of musicians that are left-handed is 0.137.
