The Men\'s Combined skiing event consists of a downhill and a slalom. Below is a histogram of slalom times for the 35 skiers in the Men\'s Combined event of the 2006 winter Olympics. Describe the shape of this distribution. Is is symmetric, skewed left or skewed right? How many skiers had times less than 92 seconds? What percentage of skiers had times of at least 94 seconds but less than 100 seconds?

Solution

A)

The tail is on the right, so it is skewed to the right.

b)

There are 6+8 = 14 skiers. [ANSWER]

***************

b)

There are 5+4+1 = 10 such skiers.

In percentage, as there are 35 skiers,

P(94<=x<=100) = 10/35*100% = 28.57142857% [ANSWER]
