A highway department executive claims that the number of fatal accidents which occur in her state does not vary from month to month. The results of a study of 171 fatal accidents were recorded. Is there enough evidence to reject the highway department executive's claim about the distribution of fatal accidents between each month?

1.The number of accidents that occur at a busy intersection is Poisson distributed with a mean of 3.7 per week. Find the probability of 10 or more accidents occur in a week? 2.The probability distribution for the number of goals scored per match by the soccer team Melchester Rovers is believed to follow a Poisson distribution with mean 0.80. Independently, the number of goals scored by the Rochester Rockets is believed to follow a Poisson distribution with mean 1.60. You...

(3.02) Examining the location of accidents on a level, 5-mile bike path shows that they occur uniformly along the length of the path. Figure 3.4 displays the density curve that describes the distribution of accidents. Height-1/5-- 0 Distance along bike path (miles) eBook Step 1: Explain why this curve satisfies the two requirements for a density curve Because it is symmetrical with respect to the vertical line at x-1.5 and the area beneath the curve does not extend 1 Because...

Answer the following questions with the given data set:
1 Distribution of accidents Accidents Weekunday Monday Tuesday Wednesday Thursday Day of the Mon Week |- | 10|29 Frequency 36 Friday Saturday 41 50 63 40 PrintDone A researcher wanted to determine whether certain accidents were uniformly distributed over the days of the week. The data show the day of the week for n =299 randomly selected accidents. Is there reason to believe that the accident occurs with equal frequency with...
The average number of accidents at controlled intersections per year is 4.6. Is this average less for intersections with cameras installed? The 52 randomly observed intersections with cameras installed had an average of 4.2 accidents per year and the standard deviation was 1.07. What can be concluded at the αα = 0.01 level of significance? For this study, we should use Select an answer z-test for a population proportion t-test for a population mean The null and alternative hypotheses would...
