Reаd the twо different scenаriоs belоw: Scenаrio 1: Chad wants to determine if there is a significant difference in the mean price of lawn mowers at Home Depot and at Lowes. He collects a random sample of 10 different lawn mowers at Home Depot and records the price for each one. Then, he goes to Lowes and finds those exact same lawn mowers, recording their prices there. Scenario 2: Chad wants to determine if there is a significant difference in the mean price of lawn mowers at Home Depot and at Lowes. He collects a random sample of 10 different lawn mowers at Home Depot and records the price for each one. Then, he goes to Lowes and takes another completely random sample of 10 lawn mowers, and records those prices. Assume the population standard deviations are unknown. Which hypothesis test is most appropriate for each scenario?
