The proportion of left handed people in the population is about 0.10. suppose a random sample of 300 people is observed. (a) what is the sampling distribution of the sample proportion (p-hat)

Step-by-step explanation:

Sampling distribution of the sample proportion :

The sampling distribution of the sample proportion has mean = and standard deviation = .

Given : The proportion of left handed people in the population is about 0.10.

i.e. p=0.10

sample size : n= 300

Then , the sampling distribution of the sample proportion will be :-

 (approx)

Hence, the sampling distribution of the sample proportion is
