Answer: First Option is correct.

Step-by-step explanation:

Since we have given that

Mean (\mu)= 70 inches

Standard deviation (\sigma)= 3 inches

Average basket ball player (\bar{X}) = 79 inches

Since it is normally distributed assume with 5% significance .

So, it becomes,

Z>\frac{\bar{X}-\mu}{\sigma}\\\\Z>\frac{79-70}{3}\\\\Z>\frac{9}{3}\\\\Z>3\\\\\therefore\ P(Z>3)=1-0.9987=0.0013

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.

What is 96.39 rounded to the nearest whole number
Y_Kistochka [10]

Answer: 96

Reasoning: To round a number you must first find out whether the number behind it is 5 or more or 4 or less. If it is 5 or more increase it if it is 4 or less leave it be. Since the number is 3 it will be left alone and round to 96.

Question: what is 96.39 rounded to the nearest whole number?

Round .6283 to the nearest hundredth
Sveta_85 [38]
The answer is-. 63
.0= tenths
.00= hundredths

how to round:

So you would loom at the 1, keep in mind that any number lower than 5 toy round down. so the answer would be 50. Now consider the number 57 you would round up because 5 or greater you would round up so it would be 60.
