Write the word or phrase that best completes each statement or answers the question 3) High temperatures in a certain city for the month of August follow a uniform distribution3) over the interval 64"F to 92'F. What is the probability that a randomly selected August day has a high temperature that exceeded 69 F Find the indicated probability 4) Assume that the random variable X is normally distributed, with mean u-50 and 4) standard deviation -16. Compute the probability P(6

Explanation / Answer

Solution:-
1) option B)

2) option c)

3) P(69 < X < 92) = (92-69)/(92-64) = 0.8214

4) P(6 < X < 70) = P((6-50)/16 < Z < (70-50)/16)
= P(-2.75 < Z < 1.25)
= 0.8914

5) p(5 < X < 7.5) = P((5-6.5)/1 < Z < (7.5-6.5)/1)
= P(-1.5 < Z < 1)
= 0.7745

6) P(Z < 0.09) = 0.5359

7) - 2.05 and 2.05
