Answer to Problem 42E

d. The Mavericks won a higher proportion of games when scoring at least 100 points $\left(\frac{43}{47}\right)$ , than when they scored fewer than 100 points $\left(\frac{14}{35}\right)$ .

Explanation of Solution

Given the table below that displays the relationship between the outcome of each game in the regular season and whether the Mavericks scored at least 100 points.

	Points scored
		100 or more	Fewer than 100	Total
Outcome of game	Win	43	14	57
	Loss	4	21	25
	Total	47	35	82

From the above table, it is evident that the Mavericks have won a higher proportion of games when scoring at least 100 points $\left(\frac{43}{47}\right)$ , than when they scored fewer than 100 points $\left(\frac{14}{35}\right)$ .
