7.38 Potential insurance fraud? Insurance adjusters are concerned about the high estimates they are receiving from Jocko’s Garage. To see if the estimates are unreasonably high, each of 10 damaged cars was taken to Jocko’s and to another garage and the estimates (in dollars) were recorded. Here are the results: Car 1 2 3 4 5 6 7 8 9 10 Jocko's 1410 1550 1250 1300 900 1520 1750 3600 2250 2840 Other 1250 1300 1250 1200 950 1575 1600 3380 2125 2600 Test the null hypothesis that there is no difference between the estimates of the two garages. Be sure to specify the null and alternative hypotheses, the test statistic with degrees of freedom, and the P-value. What do you conclude using the 0.05 significance level?

3. A particular report included the following table classifying 815 fatal bicycle accidents that occurred in a certain year according to the time of day the accident occurred. Time of Day Number of Accidents midnight to 3 a.m. 46 3 a.m. to 6 a.m. 52 6 a.m. to 9 a.m. 85 9 a.m. to noon 72 noon to 3 p.m. 76 3 p.m. to 6 p.m. 157 6 p.m. to 9 p.m. 192 9 p.m. to midnight 135 For purposes of this exercise, assume that these 815 bicycle accidents are a random sample of fatal bicycle accidents. Suppose a safety office proposes that bicycle fatalities are twice as likely to occur between noon and midnight as during midnight to noon and suggests the following hypothesis: Ha: p1 > 1/3, p2>2/3 Ha: p1 ≠1/33, p2=2/3 Ha: p1 =1/3,p2=2/3 Ha: H0 is not true. Ha: p1 >1/3,p2<2/3 x2=______? p-value______? State the conclusion in the problem context. Reject H0. There is convincing evidence to conclude that bicycle fatalities are not twice as likely to…

1. A researcher wishes to determine if the following distances (in meters) traveled by a random sample of ten world-class long jumpers are highly affected by the speed (in meters per second) at takeoff. The distances recorded from the sample long jumpers are as follows: 7.67, 8.22, 7.94, 7.16, 8.08, 7.35, 7.89, 7.76, 7.25, and 7.43. On the other hand, the speeds are recorded as follows: 8.9, 9.2, 8.1, 8.6, 9.0, 8.4, 8.8, 9.1, 8.0, and 8.2. What will be the distance, assuming that the speed is 9.4 meters per second? Round your answer to two decimal places. There is no need to place the unit. 2. A certain regression line equation has the slope equal to 720.25 and an intercept that is equal to -182.4.
