Step-by-step explanation:
The required sample size is 694.
Given a student wants to make a guess within 0.03 of the true ratio with a 95% confidence level.
Margin of Error, E = 0.03
significance level α=0.05 {95% confidence}
A given estimate of the percentage of population p is p = 0.79.
The critical value for the significance level α = 0.05 is Zc = 1.96. This can be determined using either Excel or a normal probability table.
Use the following formula to calculate the minimum sample size required to estimate the percentage of population p within the required margin of error.
n≥p(1-p)(Zc÷E)²
n=0.796×(1-0.796)(1.96÷0.03)²
n=693.1016
Therefore, the resample sizequired to meet the condition is n ≥ 693.1016 and must be an integer. From this, we conclude that the minimum sample size required is n = 694.

No circle can never be the perfect squares
Let
L--------> the length of the rectangle
W-------> the width of the rectangle
we know that
the perimeter of the rectangle is equal to
so
---------> equation 
---------> equation 
Substitute equation in equation
therefore

2w+2⋅(5w)≤96
Unknown if you wanted to be clever
on average means typically so there is data called "outliers"
Moreover it doesn't say what average percent of the day and it doesn't mention the planet, namely Earth..
there could be sloths on other planets and those other planets are likely to have different hours in the day.
