The vapor pressure of 1-chlorotetradecane at several temperatures are tabulated below.     T (ºC)     P∗ mm Hg       98.5               1    131.8                 5    148.2             10    166.2             20    199.8             60    215.5            100   What error is there in using two-point linear interpolation to find the value of vapor pressure at 185ºC?

Determine whether the outcome is a Type I error, a Type II error, or a correct decision. A test is made of H0: μ = 28 versus H1: μ ≠ 28. The true value of μ is 29 and H0 is rejected.

State the conclusion based on the results of the test. The mean of the pressure required to open a certain valve is known to be u = 6.7 psi. Due to changes in the manufacturing process, the quality-control manager feels that the average pressure has changed. The null hypothesis was rejected. Choose the correct answer below. O A. The mean of the pressure has not changed. O B. There is not sufficient evidence that the mean of the pressure required to open a certain valve has changed. O C. There is not sufficient evidence that the mean of the pressure required to open a certain valve has not changed. O D. The mean of the pressure has changed. O E. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed. O F. There is sufficient evidence that the mean of the pressure required to open a certain valve has not changed.

Describe type I and type II errors for a hypothesis test of the indicated claim. A furniture store claims that at least 40% of its new customers will return to buy their next piece of furniture. Describe the type I error. Choose the correct answer below. OA. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is at least 0.40, but you fail to reject Ho: p20.40. OB. A type I error will occur when the actual proportion of new customers who return to buy their next piece furniture is at least 0.40, but you reject Ho: p20.40. OC. A type I error will occur when the actual proportion of new customers who return to buy their next piece of furniture is no more than 0.40, but you reject Ho: p ≤ 0.40. OD. A type I error will occur when the actual proportion of new customers who return to buy their next piece f furniture is no more than 0.40, but you fail to reject Ho: p ≤0.40. Describe the type II error. Choose the correct answer…
