Chapter 2.2, Problem 3.3CYU

To determine

To get the distance would a ball have to travel to be at the 80^th percentile of Tiger Wood’s drive lengths.

Answer to Problem 3.3CYU

The distance would a ball have to travel to be at the 80^th percentile of Tiger Wood’s drive length is 310.72 yards.

Explanation of Solution

Concept Used:

  $Z$ score calculation.

  $Z=\frac{x-mean}{s\tan darddeviation}$

Calculation:

  $\begin{array}{l}8.000\approx .7995\\ Z=.84\\ .84=\frac{X-304}{8}\\ X=310.72yards\end{array}$

Conclusion:

Hence, the distance would a ball have to travel to be at the 80^th percentile of Tiger Wood’s drive length is 310.72 yards.
