Suppose X is a vector of IID random variables where each element has some PDF,
Find an example PDF such that the median is a better estimate of the mean than the sample mean.
Continuous random variable is uniformly distributed between a and b. The probability density function between a and b is.
An SRS of 100 of a certain popular model car in 1993 found that 20 had a certain minor defect in the brakes. An SRS of 400 of this model car in 1994 found that 50 had the minor defect in the brakes. Let p1 and p2 be the proportion of all cars of t..
Assuming that all other variables are held constant describe how value of z is influenced by each of the following: If alpha level is changed from a = .05 to a = .01. What occurs to boundaries for the critical regions?
At the .05 significance level, is there a difference in the mean number of miles traveled per month between Cincinnati and Pittsburgh employees? Use the five-step hypothesis-testing procedure.
the mean family income in wisconsin according to the 2011 data is about 77531 with a standard deviation for the
In performing a chi-square test of independence, as the difference between the respective observed and expected frequencies decrease, the probability of concluding that the row variable is independent of the column variable increases.
Describe which scale you would use to measure the following random variables. State reasons for your choice and whether sample scale values correspond to population values.
Determine if your survey questions are appropriate for researching your business problem, and explain why they are. Identify the level of measurement being used for each of your survey questions.
(a) Find the proportion of customers that go away empty handed. (b) Find the average time that an item is on the shelf. (c) Find the average number of items on the shelf.
Using one proportion z test to find whether or not to support the claim - There is little evidence to reject H 0 , therefore they conclude the tvs are 20 pounds on average.
Following are measurements of tensile strength in ksi (x) and Brinell hardness (y) for 10 specimens of cold drawn copper. Assume that tensile strength and Brinell hardness follow a bivariate normal distribution.
in each of the following situations the sampling frame does not match the population resulting in undercoverage. give
