A scientist is studying the relationship between the percent

A scientist is studying the relationship between the percentage of a particular type of nutrient in the soil and the eventual height of a plant. The regression equation is: Height = 5.31 + 3.34 x Percentage Which is the following is true?

Solution

1.In a test of H0:=0 vs. H1:0, the null hypothesis would be rejected at the 5% level. This is true, since the p value is less than alpha.

2.The slope of the regression line is 3.345. This is also true as the coefficient of percentage is 3.345.
