The mean and standard deviation for the heights of men in the U. S. are 70 inches and 4 inches respectively and are normally distributed. Based on this information, which of the following represents the percent of men whose heights falls between 58 inches and 66 inches to the nearest whole percent? A) 2%
B) 16%
C) 34%
D) 68%

B) 16%

Step-by-step explanation:

First, we need to standardize 58 and 66 inches using the following equation:

Where m is the mean and s is the standard deviation, so 58 and 66 are equivalent to:

Then, the percent of men whose heights falls between 58 inches and 66 inches is calculated as:

P(58<z<66) = P(-3<z<-1)

So, using the normal table, we get:

P(-3<z<-1) = P(z<-1) - P(z<-3)

P(-3<z<-1) = 0.1587 - 0.0013

P(-3<z<-1) = 0.1574

Finally, 0.1574 rounded to the nearest whole percent is equal to 16%

the answer is z7+8/5

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
