Question

tormato plants, of the same varicty, were selected at random and treated, weekly with solution in which x grams of fertilizer was dissolved in fixed quantity of water. The yield, y kilograms, of tomatoes was recoeded 4. Eight a Plot a scatterplot of yield, y, against amount of fertilizer, x.Can you explain the relationship between the two variables? Scatterplot of y vs x b. Which of the following is the best match of the correlation coefficient? L r =-0.92. iii, r = 0.55. ii.r 0.96 iv.r 0.72 c. What should be the sign of the slope in the regression equation?

Explanation / Answer

B) From the given scatter plot we can say there exists positive relationship between x and y.

So r = positive value

From diagram we can have r= 0.96

C) since r is positive then slope of the regression line will also be positive.
