Which of the following regression output values is used in computing the variance inflation factors?

The finite population correction is most useful for which of the following?   a. It adjusts the estimated mean when the sample size is a large fraction of the population size.     b. It adjusts the standard error of the mean when the sample size is a small fraction of the population size.     c. It adjusts the estimated mean when the sample size is a small fraction of the population size.     d. It adjusts the standard error of the mean when the sample size is a large fraction of the population size.

Histograms of random sample data are often used as an indication of the shape of the underlying population distribution. The histograms on the next page are based on random samples of size 30,50 and 100 from the same population. a. Using the midpoint labels of the three histograms, what would you say about the estimated range of population data from smallest to largest? Does the bulk of the data seem to be between 8 and 12 all in three histograms?  b. The population distribution from which the samples were drawn is symmetric and mound shaped, with the top of the mound at 10,95% of the data between 8 and 12, and 99.7% of data between 7 and 13. How well does each histogram reflect these characteristics?

Consider the following data: −10, −10, 0, 3, −10, 3, 3  Step 1 of 3: Calculate the value of the sample Variance. Round your answer to one decimal place. Step 2 of 3: Calculate the value of the sample deviation. Round your answer to one decimal place. Step 3 of 3: Calculate the value of the range.

1.) The Test Statistic for this data. (Round answer to 3 decimal places). 2.) The p-value for this sample. (Round answer to 4 decimal places).

If two large random samples are drawn from two populations, each having a mean of $100, the relevant sampling distribution of their difference has a mean of a. 200 b. The Sum of the 2 Sample Means C. 0 D. The difference between the two sample means.
