If the total number of books checked out of the library at your high school is 14,400 and the student population is about 2400.
Whitepunk [10]

The number of books taken by each student is 6.

<h3>What is an average?</h3>

Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The average actually determines the middle value of the data.

Given that the total number of books checked out of the library at your high school is 14,400 and the student population is about 2400.

The average is calculated by dividing the sum of the total number of items by the total counts of the items.

Average = 14400 / 2400

Average = 6

Therefore, the number of books taken by each student is 6.

Find the indicated critical z value. Find zα/2 for α = 0.08
snow_lady [41]
Refer to the diagram shown below.
The value of z that yields the expected central area takes into account the excluded areas at both tails.

Half the tail area is α/2 = 0.08/2 = 0.04.
The central area is 1 - 0.04 - 0.04 = 0.92.

From standard normal tables, obtain
z(α/2) = 1.75

Answer: 1.75
