Y= 25/4 or if you want it in decimal form it’s 6.25
Answer:
The required range is 237.5 to 275.
Step-by-step explanation:
Consider the provided information.
The average cholesterol of the target population is 200 mg and they have a standard deviation of 25 mg.
The the value of μ = 200 and the 
The company wished to test a sample of people who fall between 1.5 and 3 z-scores above the mean.
Let the value of z is 1.5.
Now use the z score formula: 
Substitute the respective values in the above formula.
Now let the value of z is 3.
Substitute the respective values in the z score formula.
Hence, the required range is 237.5 to 275.
Using proportions, it is found that he bikes:
- 28.5 miles in one and a hour.
- 47.5 miles in two and a hours.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
In this problem, the proportion is that he bikes 9.5 miles each half hour, hence:
- In one hour, he bikes 2 x 9.5 = 19 miles.
- In one and a half hour, he bikes 3 x 9.5 = 28.5 miles.
- In two hours, 4 x 9.5 = 38 miles.
- In two and a half hours, he bikes 5 x 9.5 = 47.5 miles.
