We accompanying data on x= diesel oll consumption mate measured by the drain-weigh method and y = rate measured by the Cl-trace method, both in a/he, was read from graph in an article. (a) Assuming that x and y are related by the simple linear regression model, carry out a test to decide whether it is plausible that on average the change in the rate measured by the Cl-trace method is identical to the change in the rate measured by the drain-weigh method. (Use a 0.05 .) State the appropriate null and alternative hypotheses H02?B1?=1Ha?:B1?+1H0?B1?+1H0?B1?=1H01??1?=1He??1?<1H02??1?=1Hm?H1?>1? Calcuste the test statistic and determine the Pryalue. (Round your test statistic to two decimal places and your p-value to three decinal places ) t= Prvalue a State the condision in the problem context. Fail to reject H0?. It is not plausible that ?1?=1. Fall te reject H0?. It is plausible that ?1?=1. Reject H0?. If is plausible that ?1?=1. Reject H0?, It is not plausible that P1?=1.

State the conclusian in the problem context. Fall to rojest H0?. It is not piausibie that ?1?=1. Fail to reject H0?. It is plausible that ?1?=1. Reject H0?, it is plausible that ?1?=1. Reject H0?. If is not plausble that ?1?=1. (b) Calculate the yalue of the sample correlation coefficient. (Round your answer to four decimal places.) Interpret the value of the sample correlation coefficient. There is a strong positive relationship between the results of the twa measurement methods. There is a weak positive relationship between the results of the two measurement methods. There is a weak negative relationship between the results of the two measurement methods. There is a strong negative relationship between the results of the two measurement methods.
a) The appropriate null and alternative hypotheses for a test to decide whether it is plausible that on average the change in the rate measured by the Cl-trace method is identical to the change in the rate measured by the drain-weigh method are:Null hypothesis: The slope of the population regression line is equal to 1
