If two explanatory variables have high correlation, then it’s a tip-off to watch out for multicollinearity – but not conclusive evidence. 2) See if the multiple regression model use ...

Section 10.1, Relative Maxima and Minima: Curve Sketching
... To carry out the first derivative test for a function f , we need to find the critical values first. Let x0 be a critical value of f . Next, find an interval (a, b) in which x0 is the only critical value. We need f to be continuous on the interval (a, b). Then, our function will fall into one of the ...

ANALYSIS OF VARIANCE
... Even if Ho is true (i.e. all group means are equal), there will be differences in the sample means; variability in the samples will create the differences. If Ho is true, the between group variation will estimate the variability as well as the within group variation. If Ho is false the between ...

MATH-1110 (DUPRÉ) SPRING 2011 TEST 3 ANSWERS FIRST
... You may have used the 1-PropZTest here from the calculator’s TEST menu, but it is not really accurate enough to get three significant digits for such a small sample size. To use the 1-PropZTest here, you enter p0 = .4 and x = 32 and n = 100. The readout will tell you p̂ = x/n = 0.32 and the value of ...
