Question

What statistical test would perform to test your hypothesis: average time to deliver pizza, once the order is placed, is greater than 25 minutes in the population.

Answer 1

The T-test or T statistical test should be performed to test the given hypothesis: verage time to deliver pizza, once the order is placed, is greater than 25 minutes in the population.

As we know that, a statistical test called a t-test is employed to compare the means of two groups. It is frequently employed in hypothesis testing to establish whether a procedure or treatment truly affects the population of interest or whether two groups differ from one another.

The three t-test used to compare means are the one-sample, two-sample, and paired t-tests. By using the formula

t = (m - μ) / (s/√n)

Where,

t = t-test

m = mean

m - μ = theoretical value

s = standard deviation

n = variable set size
