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.
