In the Normal model N(100,16) for IQs, what cutoff value bounds the highest 5% of all IQs?
Every Normal model is defined by its parameters: the mean and the standard deviation. Suppose that the mean ?= 20, and that 45% of the area is above 30. What is the standard deviation?
A manufacturing company is interested in predicting the number of defects that will be produced each hour on the assembly line. The managers believe that there is a relationship between the defect rate and the production rate per hour.
A research study has stated that the taxes paid by individuals is correlated at a .78 value with the age of the individual. Given this, the scatter plot would show points that would fall on straight line on a slope equal to .78.
If it is known that a simple linear regression model explains 56 percent of the variation in the dependent variable and that the slope on the regression equation is negative, then we also know that the correlation between x and y is approximately
Line A produces 30% of the plants output , whereas line B produces 45% and C poduces 25%. of te output If a samle n=100 bearings is inspected that sample and found one defective bearing, what is the prbability that the sample was taken from output
If the correlation between two variables is known to be statistically significant at the 0.05 level, then the regression slope coefficient will also be significant at the 0.05 level.
