Answer:
The mean of the sampling distribution of p is 0.75
The standard deviation of the sampling distribution of p is 0.0274
Step-by-step explanation:
According to the given data 75% of the sampled households watch sports on television at least once a month therefore the mean of the sampling distribution of p is 0.75.
In order to calculate the standard deviation of the sampling distribution of p we would have to use the following formula as follows:
Standard deviation = √ [ p ( 1 - p) / n ]
= √[ 0.75 * ( 1 - 0.75) / 250]
= 0.0274
The standard deviation of the sampling distribution of p is 0.0274.

Answer:
Step-by-step explanation:
<h3>Given</h3>
<u>The equation for simple interest:</u>
<u>And values</u>
<h3>Solution</h3>
<u>Interest amount is</u>
<u>Solving for annual interest rate</u>
- 160 = 2000*2r
- 160 = 4000r
- r = 160/4000
- r = 0.04
- 0.04*100% = 4%
Annual interest rate is 4%
