For a normal distribution with mean 425 and standard

This preview shows page 3 - 6 out of 11 pages.

For a normal distribution with mean 425 and standard deviation 50, find the probability of obtaining a value greater than 365.
6) For a standard normal distribution, find the probability of obtaining a value less than z=1.5
7) For a normal distribution with mean 100 and standard deviation 10, find the probability of obtaining a value greater than 70 but less than 80. First find the cumulative probability associated with the value 80 using the function NORM.DIST(80,B1,B2,TRUE) = 2.275%; this is the percentage of outcomes with values less than 80. Then calculate the cumulative probability 70 using the function NORM.DIST(70,B1,B2,TRUE)=0.01375%; this is the percentage of cases with values less than 70. Then find the difference between the two: NORM.DIST(80,B1,B2,TRUE)– NORM.DIST(70,B1,B2,TRUE)=0.02275-0.00135=0.02140, or 2.140%. 2.0140% of the population has values between 70 and 80. You must link directly to cells to obtain the correct answer. 8) For a normal distribution with mean 47 and standard deviation 6, find the probability of obtaining a value less than 45 or greater than 49.
