Problem 11: The number of potholes on a highway was counted to be 0.5 every 2...
Suppose that the number of potholes per one city block in the Bywater area of New Orleans follow a Poisson distribution with an average of 2.5 potholes. Find the probability of at least 1 pothole in one city block of the Bywater.
Refer to OM in Action on "NYC's Potholes and Regression
Analysis" and find the expected number of potholes based on the
regression function defined in this paragraph.
Assume resurfacing gap is = 2000, and Inches of snow is = 45
OM in Action NYC's Potholes and Regression Analysis New York is famous for many things, but one it does not like to be known for is its large and numerous potholes. David Letterman used to joke: "There is a Any...
Example 3 A survey of cars a certain stretch of highway during morning commute hours showed that 70% had only one occupant, 15% had 2, 10% had 3, 3% had 4, and 2% had 5. Let X represent the number of occupants in a randomly chosen car. 1. Find the probability mass function of X, and graph it. 2. Find the probability that the car had at least 3 occupants. 3. Find the probability that the car had at most...
Mean values and rms fluctuations. Every day for 20 days I counted the number of spiders in my office and recorded the following daily populations: 2, 8, 2, 6, 3, 5,7, 2, 2, 7, 5, 8, 6, 3, 5, 8, 0, 9, 3,1 (a) Find the mean population (or ф ) defined by where i is the J measurement and N is the total number of measurements. (b) For statistical mechanics, a more useful (but equivalent) definition of the population's...
HW09: Problem 3 Problem Value: 3 point(s). Problem Score: 0%. Attempts Remaining: 3 attempts. (3 points) The Highway Safety Department wants to study the driving habits of individuals. A sample of 26 cars traveling on a particular stretch of highway revealed an average speed of 67.3 miles per hour with a standard deviation of 6.1 miles per hour. Round to 4 decimal places. 1.Calculate a 99% confidence interval for the true mean speed of all cars on this particular stretch...
A fair coin is tossed 10 times and the number of heads is counted. Complete parts (a) through (d). a. Use the binomial distribution to find the probability of getting 5 heads. (Round to four decimal places as needed.) b. Use the binomial distribution to find the probability of getting at least 5 heads. (Round to four decimal places as needed.) c. Use the binomial distribution to find the probability of getting 5 to 7 heads. (Round to four decimal...
In order to test whether a certain coin is fair, it is tossed ten times and the number of heads (X) is counted. Let p be the "head probability". We wish to test the null hypothesis: p = 0.5 against the alternative hypothesis: p > 0.5 at a significance level of 5%. (a) Suppose we will reject the null hypothesis when X is smaller than h. Find the value of h. (b) What is the probability of committing a type...
Previous Problem Problem List Next Problem (1 point) The U.S. National Highway Traffic Safety Administration gathers data concerning the causes of highway crashes where at least one fatality has occurred. From the 1998 annual study, the following probabilities were determined (BAC is blood-alcohol level): P(BAC =0|Crash with fatality) = 0.613 P(BAC is between .01 and .09|Crash with fatality) = 0.335 P(BAC is greater than .09|Crash with fatality) = 0.054 Suppose over a certain stretch of highway during a 1-year period,...
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?
