Answer:
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
