A manufacturer makes two models of an item : Model I, which accounts for 80% of unit sales, and model II, which accounts for 20% of unit sales. Because of defects, the manufacturer has to replace or exchange 10% of its model I and 18% of its model II. If a model is selected at random, find the probability that it will be defective?
A research analyst regresses the number of calls for service (Y) on the Fahrenheit temperature at 4:00 in the afternoon (X). The regression equation finds: Y = 62 + 2.4 X with an r 2 of .67
How do hypothesis-testing procedures differ for the population mean when the population standard deviation is known or unknown? What is the relationship between two-sided hypothesis tests for means and confidence intervals?
Determine the probability of randomly selecting 10 production employees on hot summer day and determining that none of them are absent?

The study found that men who had participated in some vigorous activity at least twice a week in high school, college, and up to age 40 had a 60% reduced risk of Parkinson's disease developing. The study found no such reduction for women. What typ..
We wish to construct a 90% confidence interval on the mean of a population known to be normally distributed based on a sample of 20 observations having a sample mean of 8 and a sample standard deviation of 2. What is the standard error?
Suppose a population proportion is .40, and 80% of the time when you draw a random sample from this population you get the sample proportion of .35 or more.
If 20 measurements are taken and their standard deviation is 1.8, is there enough evidence to reject the claim that her standard deviation is within the limit at ∞ = .01?
Assume the least squares equation is Y' = 10 + 20X. What does the value of 10 in the equation indicate?
