Question

A normal distribution has a mean of 50 and a standard deviation of 4. Solve the following three parts?

1. Compute the probability of a value between 44.0 and 55.0.

(The question requires finding probability value between 44 and 55. Solve it in 3 steps.

In the first step, use the above formula and x = 44, calculate probability value.
In the second step repeat the first step with the only difference that x=55.

In the third step, subtract the answer of the first part from the answer of the second part.)

2. Compute the probability of a value greater than 55.0.

Use the same formula, x=55 and subtract the answer from 1.

3. Compute the probability of a value between 52.0 and 55.0.

(The question requires finding probability value between 52 and 55. Solve it in 3 steps.

In the first step, use the above formula and x = 52, calculate probability value.
In the second step repeat the first step with the only difference that x=55.

In the third step, subtract the answer of the first part from the answer of the second part.)
