Suppose a shop owner claims that an equal number of customers come into his shop each weekday. The null and alternative hypotheses are stated in terms of the population variance (or population standard deviation). Φ= √ χ2 n ϕ = χ 2 n. To test this hypothesis, he records the number of customers that come into the shop on a given week and finds the following: In table 8.1 for sample a this is 155/289 = 0.5363.

Web what is hypothesis testing? And if we know that χ2 = 9.25 χ 2 = 9.25 and that n = 32 n = 32, then putting them into the formula we get: Suppose a shop owner claims that an equal number of customers come into his shop each weekday. Φ= √9.25 32 ϕ = 9.25 32.
