Suppose the heights of the members of a population follow a normal
distribution. If the mean height of the population is 68 inches and the
standard deviation is 4 inches, 95% of the population will have a height within
which of the following ranges?
O
A. 52 inches to 84 inches
B. 60 inches to 76 inches
C. 64 inches to 72 inches
O
D. 56 inches to 80 inches

B. 60 inches to 76 inches.

Step-by-step explanation:

95% of the estimations would be inside 2 standard deviations of the mean.

The mean = 68

Standard deviation = 4

2 x 4 = 8

68 - 8 = 60

68 + 8 = 76.

Hope this helps & best of luck!

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
