You measure 22 randomly selected textbooks' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 12.6 ounces. Based on this, construct a 99% confidence interval for the true population mean textbook weight.

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 value of x is 28.2
