CHALLENGE

There are sample data about the depth of plowing the fields for winter crops (X, cm) and yield (Y. n \\ n):

X 10 15 20 25 30

Y May 10 16 20 24

For a = 0.05 to establish the significance of the statistical relationship between the signs of X and Y.

If symptoms are correlated, build the regression equation, and explain its meaning.

Make a forecast yield of wheat in the plowing depth of 22 cm.
