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:
<em>150 miles</em>
Step-by-step explanation:
Given the scale on the map using the conversion factor
1 inch = 50 miles
We are to find the equivalent miles between the cities in miles if the distace is 3inches
3inches = x
Divide both expressions
1/3 = 50/x
Cross multiply
x = 3 * 50
x = 150
<em>Hence the actual distance between these two cities in miles is 150 miles </em>
