31.5 is the answer to your problem
Answer: 
Step-by-step explanation:
Given : Significance level : 
Sample size : n=85
Critical value : 
Sample mean : 
Standard deviation : 
The confidence interval for population mean is given by :-
Thus, the 95% confidence interval for the true mean cholesterol content, μ, of all such eggs =
Hence, we conclude that the true population mean of amount of cholesterol lies between 182.356 and 197.644.
Suppose an individual's retirement account with a balance of $165,000 is transferred to a new investment plan that pays 8% interest compounded annually. How much will the account be worth after 3 years? (Remember, the formula is A = P(1 + r)t.)
The relative frequency of the marked elks are:
- Male Elk = 7/30
- Female Elk = 4/15
- Adult Elk= 173/450
- Baby Elk = 26/22
<h3>How to determine the relative frequency?</h3>
From the complete question, we have:
- Male = 105
- Female = 120
- Adult = 173
- Baby = 52
- Total = 450
The relative frequency of each is then calculated as:
Male Elk = 105/450
Male Elk = 7/30
Female Elk = 120/450
Female Elk = 4/15
Adult Elk= 173/450
Baby Elk = 52/450
Baby Elk = 26/22
<h3>The number of Elks in the park</h3>
Using the data in (a), we can conclude that:
There are 105 male, 120 female, 173 adult, and 26 baby in the park
