A horticulturist is studying the relationship between tomato plant height and fertilizer amount. Thirty tomato plants grown in similar conditions were subjected to various amounts of fertilizer (in ounces) over a four-month period, and then their heights (in inches) were measured.

1. Estimate the regression model:Height = ₀ + ₁Fertilizer + .

2. At the 1% significance level, determine if an ounce of fertilizer increases height by more than 3 inches. First, specify the competing hypotheses.

A. H₀: ₁ = 3; H_A: ₁ 3

B. H₀: ₁ 3; H_A: ₁ > 3

C. H₀: ₁ 3; H_A: ₁ < 3

3. Calculate the value of the test statistic.

4.Find the p-value.

• 0.05p-value < 0.10
• p-value < 0.01
• p-value0.10
