Teit-Melts Schoenberger-Microsoft Edg4 Intro to Probability and Statistics Section T1 Fall 2017 Quiz: Chapter 11 Review Quiz Submit G This Question: 1 pt 5019(4 complete) This Quiz: 9 pts pos To illustrate the affects of driving under the inuence (DUI) of alcohol, a police officer brought a DUJIl simulator to a local high school. Student reaction time in an emergency was measured with unimpaired visian and also while wearing a pair of special goggles to simulate the effects of alcohol on vision. For a random sample of nine teena Complete parts (a) and (b) Nole. A normal probability plat and boxplot of the data indicate that the differences are approximately normally distributed with no outlers gers, the time fin seconds) raquired to bring the vehicle to a stop from a spood of 60 miles per hour was recorded. Click the icon to view the data table (a) Whather the student had unimpaired vision or ware goggles first was randomly selected. Why is this a good idea in designing the expeniment? O A. This is a good idea in designing the experiment because reaction Simes are different. O C. This is a good idea in designing the experiment because the sample size is not large anough (b use a 95% confidence interval to test there is a diference in braking tine with r paired vis on and normal is on where the d i r nces are com The 95% confidence interval is ULD R State the appropriate conclusion. Choose the correct answer below O There is insulficient evidence to conclude there is a difference in braking time with impairad vision and normal vision. O There is sufficlent evidence to conclude there is a difference in braking time with impaired vision and normal vision O B. This is a good idea in designing the experiment because it controls for any "1earmning that may occur in using the simulator. computed as "impaired minus normal. ) (Round to the nearest thousandth as needed Data Table Subject 1 23 45678 9 Normal, X, 447 4.24 458 465 431 483 459 500 479 Impaired, Y, 577 585 551 529 590 549 523 5.61 563 Clck to select your answers) Type here to search 12/4/2017

Explanation / Answer

Solution:-

d =  0.98 , sd = 0.4129 n = 9 , df = n-1 = 9-1 = 8 t = 2.31

a) option B

b)   d+/- t * sd/sqrt(n) = 0.98 +/- 2.31* 0.4129/sqrt(9) = (0.66 , 1.30)

c) option A.
