Answer:
Bethany did not do better than Richie because her average score was less than his.
Step-by-step explanation:
Average Value
The average or mean value of m successes out of n tries is given by:
[tex]\displaystyle \bar x=\frac{m}{n}[/tex]
During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:
[tex]\displaystyle \bar x=\frac{12}{15}=0.8[/tex]
Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:
[tex]\displaystyle \bar x=\frac{8}{11}=0.72[/tex]
Bethany did not do better than Richie because her average score was less than his.
The person that did better is Richie. This is because the percentage of free throws made by Richie is higher than that of Bethany.
In order to determine who did better, the percentage of free throws made has to be determined.
The percentage of free throws made by Richie =( 12 / 15) x 100 = 80%
The percentage of free throws made by Bethany = [(8-3) / 8] x 100 = 62.50%
