A construction crew in northern Canada is about to start road work on a logging road. Being minor, their work will only take a single day. Since this road is far from civilization, not many vehicles drive on it. The amount of daily traffic follows a poisson distribution with ?=5.4.

Given this Poisson distribution, what is the probability that the number of cars stopped by this construction will be 5?

Enter your answer in decimal form using three decimal places. For example, if your answer is 23.24%, you should enter .232 in the box below.

What is the probability that the construction crew will stop more than 4 cars?

Enter your answer in decimal form using three decimal places. For example, if your answer is 23.24%, you should enter .232 in the box below.

A third small construction crew in northeastern Canada is about to start road work on a road that connects two small fishing villages. Being minor, their work will only take one day. Since this road is in a remote area, not many vehicles drive on it. The amount of daily traffic follows the following distribution.

Number of Drivers               Probability
----------------------------------------------------------
        1                                         0.211
        2                                         0.193
        3                                         0.163
        4                                         0.22
        5                                         0.213


Given this distribution, what is the probability that the number of cars stopped by this construction will be 1 or 3?

Enter your answer in decimal form using three decimal places. For example, if your answer is 23.24%, you should enter .232 in the box below.

-----------------------

What is the probability that the construction crew will stop more than 2 cars?

Enter your answer in decimal form using three decimal places. For example, if your answer is 23.24%, you should enter .232 in the box below.

(PLEASE answer all questions and I will give you a thumbs up!) A small construction crew in northwestern Canada is about to start road work on a mining road. The work is not too difficult and it will only take one day. Since this road is in a pretty remote area, not many vehicles drive on it. The amount of daily traffic follows a uniform distribution with daily vehicles ranging from 4 to 15. Given this discrete uniform distribution, what...

The mean work week for engineers in a start-up company is believed to be about 60 hours. A newly hired engineer hopes that it's shorter. She asks 10 engineering friends in start-ups for the lengths of their mean work weeks. Based on the results that follow, should she count on the mean work week to be shorter than 60 hours? Conduct a hypothesis test at the 5% level. Data (length of average work week): 70; 50; 55; 65; 65; 55;...
