A horticulturist is studying the relationship between tomatoplant height and fertilizer amount. Thirty tomato plants grown insimilar conditions were subjected to various amounts of fertilizer(in ounces) over a four-month period, and then their heights (ininches) were measured. (You may find it useful toreference the t table.)

a. Estimate the regressionmodel: Height= β0 + β1Fertilizer+ ε. (Round youranswers to 2 decimal places.)
b-1. At the 10% significance level, determineif an ounce of fertilizer increases height by more than 3 inches.First, specify the competing hypotheses.
multiple choice 1
H0: β1 =3; HA: β1 ≠3
H0: β1 ≤3; HA: β1 >3
H0: β1 ≥3; HA: β1 <3
b-2. Calculate the value of the teststatistic. (Round intermediate calculations to atleast 4 decimal places and final answer to 3 decimalplaces.)
b-3. Find the p-value.
multiple choice 2
0.05 p-value< 0.10
0.025 p-value< 0.05
0.01 p-value< 0.025
p-value < 0.01
p-value 0.10
b-4. At the 10% level ofsignificance, what is the conclusion to the test?
