Adult entrance fees to amusement parks in the United States are normally distributed with a population standard deviation of 2.5
kondor19780726 [428]

Answer:  1.509

Step-by-step explanation:

The formula of Margin of Error for (n<30):-

E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n= 22

Level of confidence = 0.99

Significance level : \alpha=1-0.99=0.01

Using the t-distribution table ,

Critical value : t_{n-1, \alpha/2}=t_{21,0.005}= 2.831

Standard deviation: \sigma=\text{ 2.5 dollars }

Then, we have

E=( 2.831)\dfrac{2.5}{\sqrt{22}}\approx1.509

Hence, the margin of error for a 99% confidence interval for the population mean =1.509
