Step-by-step explanation:
Data given
n=20 represent the sampel size
represent the sample mean for the independent variable (IQ score of the husband)
represent the sample mean for the dependent variable.
r =0.925 represent the correlation coefficient
Solution to the problem
The general expression for a linear model is given by:

Where
is the intercept and
the slope
For this case we have a linear model given by the following expression:

Where -3.34 is the intercept and 1.07 the slope. In order to find the best predicted value when X = 91 we just need to replace into the equation the value of 91 and we got this:

On this case is the best predicted value because
we have an unbiased estimator.
You have a 1 in 50 chance (ie A)
Explanation:
Let's start with the first bag. In it sits 5 numbers. So, you have a 1 in 5 chance that the number picked will be yours.
Now, let's consider the second bag. You have 10 different numbers and only one of yours may be picked. Hence, you have a 1 in 10 chance that yours will get picked.
Since we want them simultaneously, we will need to multiply the two probabilities together, yielding a 1 in 50 chance.
