<h2>Solution</h2>

A <em>conditional relative frequency table</em> shows the relative frequencies determined upon a row or column.

There are two types of relative conditional frequency table: 1) row conditional relative frequency, and 2) column conditional relative frequency.

When you divide the joint frequency by the marginal frequency of the column total you have the row conditional frequency table. When you dividethe joint frequency by the row total you have the colum conditional frequency table.

In a row conditional relative frequency each total of the right hand column equals 1. This is the case of the second table.

In a column conditional relative frequency each total of the bottom row equals 1. This is not happening with any of the shown tables.

Hence, only the second table could be a conditional relative frequency table.

During the basket ball season, morgan made 3 times as many 2 point baskets as she made 3 point baskets and free throws combined.
pogonyaev

Answer: Morgan make (66) 2point baskets.

Explanation:

It is given that during the basketball season, morgan made 3 times as many 2 point baskets as she made 3 point baskets and free throws combined.

Let the number of 2point basket be x, the number of 3point basket be y and the number of free throws be z.

x=3(y+z)

If she made 14 free throws and eight 3point baskets, then the number of 2point did she make is,

x=3(14+8)

x=3(22)

x=66

Therefore, the number of 2point baskets make by morgan is 66.
