The mean distance for tee shots on the 1999 men's PGA tour is 272.2 yards with a standard deviation of 8.12 yards. Assuming that the 1999 tee-shot distances are normally distributed answer the following questions: a. Determine the quartiles of the driving distances b. Find the 95 percentile. c. Obtain the third decile (i.e. 30th percentile). d. Interpret your answers in parts a-c Use Excel to answer questions (3), (4) and (5) a-c above (i.e. repeat the hand- calculations using Excel. Label questions appropriately in excel worksheets Hand in Excel output. 6. Exercises for Recitations 1. Using standard normal probability table find the area that a. lies to the right of -1.37 b. lies to the left of 1.42 c lies between 1.35 and 0.19 d.lies either to the left of 2.5 or to the right of 1.78 2. Complete the following table (read closest value from Normal table) 1645 1.96 As reported by the US National Center for Health Statistics, males who are 6 ft

Explanation / Answer

1.

We use the normal distribution to solve the problem:

a. P(Z>-1.37) = 1-P(Z<=-1.37) = 1-.91466 = .82934

b. P(Z<1.42) = .9222

c. P(-1.35<Z<.19) = .5753-.0885 = .4868

d. P(Z<-2.5 or Z>1.78) = .00621+.03754 = .04375
