Assume that the number of customers who arrive at a water ice stan d follows the Poisson distribution with an average rate of 6.4 per 30 minutes.
a. What is the probability that exactly five customers will arrive during the next 30 minutes?
b. Compute the expected value
c. Compute the variance
d. Compute the standard deviation
Expected value, variance and standard deviation.A volunteer ambulance service handles 0 to 5 service calls on any given day. The probability distribution for the number of service calls is as follows.
Figure out the best means to calculate the reliabilty of our work load index ie a measure of work load per empolyee per hour - is there a statistical measurement i could use? i really need to verify the accuracy of this measurement.
Would this be a T-value distribution? Can you take me through the steps to determine upper and lower limits of a 95% confidence interval?
assume that a procedure yields a binomial distribution with a trial repeated ntimes. use a binomial probabilities table

Find the difference between the actual y value and the predicted y value for each individual, square the differences and add the squared values to obtain ss residual.
Henry performed a two-tailed test for an experiment in which N = 24. He could not find his table of t critical values, but he remembered the tcv at df = 13. He decided to complete his obt.with this tcv. Is he more likely to make a type I or II err..
Look at the dataset. What design is it? What else do you notice and obtain the (appropriate) ANOVA table to be used in the analysis.
Assume the FDA has established 200 grams of fruits and vegetables as minimum daily intake. Determine the probability woman selected will meet this minimum intake?
One set represents the weight before treatment. The other set represents the weight after treatment. In a case like this use a paired-sample t-test.
