Answer: 0.1
Step-by-step explanation:
Given : A Houston department store sampled 80 items sold in January and found that 8 of the items were returned.
In other words, sample size : <em>n</em>=1040
Number of items returned : <em>x</em>= 8
Let <em>p</em> be the proportion of items returned for the population of sales transactions at the Houston store.
As per sample , the sample proportion of items returned for the population of sales transactions at the Houston store is :

As we know that , <em>the sample proportion is the best estimate of the population proportion.</em>
Therefore,a point estimate of the proportion of items returned for the population of sales transactions at the Houston store is 0.1.
Answer: 0.750
Step-by-step explanation:
Let p be the population proportion .
We are given that a sample of 400 voters reveals that 300 would support her in the November election.
Then the sample proportion for this situation will be :-

Since the sample proportion is the best point estimate for the population proportion.
Therefore, the estimated value of the population proportion =0.750
