Question

A random variable X follows the uniform distribution with a lower limit of 550 and an upper limit of 600.

a.) calculate the mean for the distribution. (Round intermediate calculation for Standard deviation to 4 decimal places and final answer to 2 decimal places.)

b.) What is the probability that X is less than 560? (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)

b.) What is the probability that X is less than 560? (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)

Explanation / Answer

a)

We are given,

a = 550

b = 600

Mean = (a+b)/ 2 = (550+600)/2 = 575

Answer: 575

b)

P ( x <560)

= (560 -550)/(600-550)

= 10/50

= 0.2

Answer: 0.2
