Question 1 25 pts A light bulb manufacturers' supplier offers two types of glass, clear and frosted. Suppose an engineer wants to compare the average glass strength (MPa) of each type of glass. The engineer samples 36 clear bulbs and 40 frosted bulbs. The sample mean of the clear bulb glass is 7.35 MPa and the sample mean of the frosted glass is 7.65 MPa. Historically, the standard deviations of the clear and frosted glass is .50 and 64, respectively. Run a test at a 5% significance level to test that the clear and frosted bulb glass have the same strength. What is the null and alternative hypotheses for this test? O HOUF - HC # 0 HOWF - HC = 0 O HOUF - HO = 0 HOWF - HC > 0 HOWF - HC 2 0 HUF - HC
