... mean height of all college students to be 174.5 centimeters? Solution: By the previous part, we can assert with 98% confidence that the error |x̄ − µ| is no larger than zα/2 √sn = 2.27. This is again because the sample size is sufficiently large so that the sample standard deviation is a good estima ...

... Note that a high degree of correlation does not imply anything about a causal relationship between x and y, but what it does do is enable one to predict values of y from x with a high degree of probability that they will be correct. Of course, some variables will be positively correlated, with r hav ...

Regression
... When you did your excel graphs on variables from the Class Vital Data, you put in a trend line and the R2 value. The R2 value is called “R squared” by scientists. It tells how closely the data are clustered around the trendline, or the strength of the regression. This clustering is a measure of vari ...
