This would be a great question to just plug into a calculator. I'm sure you will find the answer quite easily if you use a calculator.
Answer:
The reasonable range for the population mean is (61%, 75%).
Step-by-step explanation:
The interval estimate of a population parameter is an interval of values that consist of the values within which the true value of the parameter lies with a certain probability.
The mean of the sampling distribution of sample proportion is,
.
One of the best interval estimate of population proportion is the 95% confidence interval for proportion,

Given:
n = 150
= 0.68
The critical value of <em>z</em> for 95% confidence level is:

Compute the 95% confidence interval for proportion as follows:


Thus, the reasonable range for the population mean is (61%, 75%).
Distance traveled = 70 m
Number of rotations = 29
We know, Circumference * Number of rotations = Distance traveled
So, C = 70 / 29
C = 2.41 m
Now, we know, diameter = C / π
So, d = 2.41/3.14 = 0.768
In short, Your Answer would be: 0.8 m
Hope this helps!
The equation you would write would be:
