Question

O B Question Help To illustrate the effects of driving under the influence (DUI) of alcohol, a police office brought a Dul simulator to a local high school Student reaction time in an emergency was measured with unimpaired vision and also while wearing a pair of special goggles to state the effects of alcohol on vision for a random sample of nine teenagers, the line in seconds) required to bring the vehicle to a stop from a speed of 60 miles per how was recorded Note: Anormal probability plot and beplot of the data indicate that the differences are approximately nomaly distributed with no others. Click the icon la viw the durable (a) Whether the student had usimpaired vision or wore goggles first was randomly selected Why is this a good idea in designing the Data Table - X O. This is a good ideas designing the experiment because reaction times we diferent OB. This is a good idea in designing the experiment because it controls for any "haring that may occur in using the simulator OC. This is a good idea in designing the experiment because the sample size is not forge enough (Use a confidence Werval to there is a difference in braking time with impaired vision and normal vision where the 2 3 4 5 6 7 8 9 Normal 4.49 434 4.50 4.56 431 4.33 459 5.00 4.79 The lower bounds Impaired. Y 50505 5.45 529 5.90 5.9 523 563663 The upper bounds Round to the nearest thousandth as needed) State the appropriate conclusion Choose the correct answer below Pant Done 1 There is sent evidence to conclude there is a diference in braking time with impaired vision and normal vision

Answer 1

Solution: Normal xi 4.49 4.34 | 4.58 456 4.31 (4.83/4.595 4.79 Impaired Y; 5.06 soos 5.45 5.29 5.90 Souq 5.23/5.63/5.63 d=Yi-xi 0:57 0.7 0.87 0.73 1:59 0.66 0.64 0.63 0.84 a> This is good idea in designing the experiment because reaction times are different option A by from the sample, Mean, = Ed 0.57 +0.71 +--- +0.84 9 d = 0.8ouy Standard Deviation, s= (hinn? +0.84-0.8o4y)? - 0.57-0.8044) + 9-1 S=0.3103 Margin of Error Error, E=tyx tapti na fi toos = 2-2281] 52.2281 X 03103 ra ES 0.2304 qst Confidence interual, CI=dze -0.8044 +0.2304 =66.574, 1:0348] c 4 lower bound = 10:574 Upper bound= (1.0348 ) Their is sufficient Evidence to conclude there es difference in braking time with impaired vision & normal option a
