A high school basketball coach is selecting his team. The minimum and maximum height requirements are as follows:
daser333 [38]

Answer:

B. About 2% of the boys are eligible to be a small forward on the team

Step-by-step explanation:

Recall : 1 feets = 12 inches

Point guard = 6’2" – 6’6" tall = 74 - 78 inches

Mean = 70 ; Standard deviation = 4

Z = (x - mean) / standard

P(x < 74) = (74 - 70) / 4 = 1

P(x < 78) = (78 - 70) / 4 = 2

0.97725 - 0.84134 = 0.13591

Small forward : 6'6" = 78 inches

P(x ≥ 78) = (78 - 70) / 4 = 2

P(z ≥ 2) = 0.02275 = 2.275% about 2%

Centre : 6'8" = 80

P(x ≥ 80) = (80 - 70) / 4 = 2.5

P(z ≥ 2.5) = 0.0062097 = 0.62%

Answer:

Solution given:

x. \:\:\: f. \:\:\: fx

13. \:\:\: 15. \:\:\: 195

14.\:\:\: 42 \:\:\: 588

15. \:\:\: x. \:\:\: 15x

16. \:\:\: 10. \:\:\: 160

17. \:\:\: 3. \:\:\: 51

. n=70+x. \sum=994+15x

we have

mean=sum/n

14.44=\bold{\frac{\sum}{n}}

14.44=\bold{\frac{994+15x}{70+x}}

doing crisscrossed multiplication

(70+x)*14.44=994+15x

1010.8+14.44x=994+15x

15x-14.44x=1010.8-994

0.56x=16.8

x=16.8/0.56

x=30
