Test the significance of the correlation coefficient.
Then use math test scores (X) to predict physics test scores
(Y). Do the following:
Create a scatterplot of X and Y.
Write the regression equation and interpret the regression
coefficients (i.e., intercept and slope).
Predict the physics score for each....

This is my dataset
Find mean, median, mode, variance, standard deviation,
coefficient of variation, range, 70th percentile,
3rdquartile of the data and skewness and define what
each of these statistics measure. For example, mean is a measure of
the central tendency, what about the rest?

What is the
(population) standard deviation of the data?
Please specify your
answer in decimal terms and round your answer to the nearest
thousandth (e.g., enter 12.3 percent as 0.123).
Note that the correct
answer will be evaluated based on the full-precision result you
would obtain using Excel.
