![]() ![]() And this is a, an interesting problem with the Poisson distribution. (d) Test the statement that the Poisson distribution fits the sample data. (a) The civil engineer wants to use a Poisson distribution to represent the probability of $r$, the number of accidents per day. A random sample of 90 days gave the following information. Let $O$ represent the number of observed accidents per day based on local highway patrol reports. ![]() Let $r$ be a random variable that represents number of accidents per day. Long-term history indicates that there has been an average of $1.72$ accidents per day on this section of the interstate. Highway Accidents: Poisson Distribution A civil engineer has been studying the frequency of vehicle accidents on a certain stretch of interstate highway. DO NOTĪnswer these questions with a simple "Yes" or "No" if you do, it Type of error (Type I or II) if you did make an error. You need toĮxplain why or why not you made an error as well as identifying the If so, which error? (Answer in complete sentences. If the true difference in means was 0, did you make an error? State your conclusion in context of the problem. State whether you reject or do not reject the null (Copy, paste, and use the resultsįound in the Session window after your answer. State the significance level for this problem. State the null and alternative hypotheses.
