Describe type I and type Il errors for a hypothesis test of the indicated claim. A lumber store claims that no more than 25% of its new customers will return to buy their next order of lumber. Describe the type I error. Choose the correct answer below. O A. Atype l error will occur when the actual proportion of new customers who retum to buy their next order of lumber is no more than 0.25, but you reject Ho: ps 0.25. O B. Atype l error will occur when the actual proportion of new customers who return to buy their next order of lumber is at least 0.25, but you fail to reject Ho: p20.25. O C. Atype l error will occur when the actual proportion of new customers who return to buy their next order of lumber is no more than 0.25, but you fail to reject Ho:ps0.25. O D. Atype I error will occur when the actual proportion of new customers who return to buy their next order of lumber is at least 0.25, but you reject Ho: p20.25. Describe the type Il error.

Use technology to find the P-value for the hypothesis test described below. The claim is that for a smartphone carrier's data speeds at airports, the mean isµ= 19.00 Mbps. The sample size is n= 11 and the test statistic is t= - 1.808. P-value = (Round to three decimal places as needed.)

Q1) One-Sample t-Test: I am shopping for a new sedan and would like to get one with excellent miles per gallon (MPG). I heard that Japanese cars tend to be more fuel efficient than American cars, so I collected MPG data on a random sample of 12 Japanese 4-cylinder sedan models (listed in the table below) to be compared to the American car statistics. I would like to see if there is a significant difference, in either direction, between Japanese sedans and American sedans. The US Environmental Protection Agency reported that the average MPG for American sedans in 2017 is μ = 29. I set the significance level at a = .10 for a two-tailed hypothesis test. Hint: Because we know the population mean for the American cars but not the standard deviation, we cannot conduct a Z test but should perform a one-sample t-test instead. Japanese car model 1 2 3 4 5 6 7 8 9 10 11 12 MPG 32 30 27 36 35 28 32 28 32 28 32 32
