Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
Mean
= 70 inches
Standard deviation
= 3 inches
Average basket ball player
= 79 inches
Since it is normally distributed assume with 5% significance .
So, it becomes,

At 0.05 level of significance , 0.0013 = 0.13% of the adult male population is taller than the average basketball player .
Hence, First Option is correct.
Answer:6060 foot-pounds

Answer:
1249. 5 inches
Step-by-step explanation:
Pole length , Pl = 2 fts
Pole shadow, Ps = 20 in = (0.0833 * 20) = 1.666 ft
Tower length, Tl = 125 ft
Tower shadow, Ts = x
Pl / Ps = Tl/ Ts
2/ 1.666 = 125 / x
Cross multiply
2x = 125 * 1.666
2x = 208.25
x = 104.125 ft
x = 104.125 * 12 = 1249. 5 inches
