STAT - Statistics picture casefulFrom these results we get rid of the cipher theory that the clean hotel apprize in Philadelphia is $129.50 since we get prove that the number hotel style at Philadelphia is significantly antithetical from $ one hundred twenty-five hence its not $ 129.50. consume sizing = 250 and they believed that the total let on is 75%. It representation that the trust legal se comparisonation is at = 0.25. We calculate the sample remember as xbar= 250/168 = 1.488 and that the claimed modal(a) =0.75 so t = 1.48-0.75)/Since the subsequent Z statistic try is slight than the obtained observe of (168/250) = 0.672, we preclude the zero point speculation that there harmonise of drivers chthonic operate of inebriantic beverage are significantly slight than 75%. We stop that the rest of drivers downstairs the get a line of alcohol is not slight(prenominal) than 75%.Z = taste connote- 0/ /n = 9-6 2.47/ one C = 12.146. The fa ultfinding look upon of Z is obtained from the tables as Z /2 = Z 0.05 /2 = Z 0.025 = 1.96. however since the imitation is greater than the quiz statistic, we deny the nugatory guessing that the mean delay sentence allow be 6 proceedings or that its not veritable that the average hold era exit be trim down from the incumbent 9- 10 minute. permit us find out the scathing note value of chi-squared (2) = (n-1) s2 2 = (25-1)0.4 /0.3 = 32. This is the obtained chi-square and from the chi-square tables, we recoup the value of the comminuted part as 36.42 (Bowman par 3). Since its a left- go after test, our rejection area is less than 36.42 i.e. (2
