A sample of 64 was taken from a population, with the mean of the sample being 25 and the standard deviation of the sample being 2. What is the 95%
confidence interval for the mean of the population?

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

the answer is d. 75%

0.02
