The following three questions (i.e., questions 1-3) refer to the following information:
The random variable X, representing the number of accidents in a certain intersection in a week, has the following probability distribution:
x 0 1 2 3 4 5
P(X=x) 0.20 0.30 0.20 0.15 0.10 0.05
Question 1: Point value: 10
1.) What is the probability that in a given week there will be at most three accidents?
(a) 0.70
(b) 0.85
(c) 0.35
(d) 0.15
(e) 1.00
2.) By the third day of a particular week, 2 accidents have already occurred in the intersection. What is the probability that there will be less than a total of 4 accidents during that week?
(a) 1.00
(b) 0.90
(c) 0.85
(d) 0.70
(e) 0.50
3.) On average, how many accidents are there in the intersection in a week?
(a) 5.3
(b) 2.5
(c) 1.8
(d) 0.30
(e) 0.1667
What is the probability that a fish is *exactly*, *precisely* to any level of accuracy or measurement, 12.0 inches long?
Recognize independent variable and dependent variable for this experiment. Think in your head what influences what? Or, what causes what? Cause is independent variable.
If probability the first truck is available is= .75, probability the second truck is available is= .50, and probability both are available is= .30, determine the probability which neither truck is available?
Determine whether the difference in proportions is significant at the 0.05 level.
If an apartment is selected at random, what is the probability that it is not a 2 bedroom apartment on the 2nd floor?
Find the slope and vertical axis intercept of the linear function
A teacher wants to know if students in her biology class did significantly better on an exam after instruction using authentic learning. The scores pre and post test are listed below. Based on an α = .05, what can the teacher conclude?
Write the Lagrangian for a one-dimensional particle moving along the x-axis and subject to a force F=-kx (with k possitive). Find the lagrange eqn of the motion and solve it.
Suppose that a certain college class contains 45 students. Of these, 26 are sophomores, 25 are chemistry majors, and 7 are neither. A student is selected at random from the class.
Assume the population standard deviations are not the same. At the .05 significance level, is there a difference in the mean waiting time?
Find the 90% confidence interval for the standard deviation for the time it takes an inspector to check a bus for safety if a sample of 27 buses has a standard deviation of 6.8 minutes.
Fast Service, a chain of automotive tune-up shops, advertises that its personnel can change the oil, replace the oil filter, and lubricate any standard automobile in 15 minutes, on the average.
