Hello I really need help with this problem I am very confused!

An experiment was conducted see the effect on fertilizer on production of Mameys.

H₀ : fertilizers have no impact on mamey production.

H₁ : fertilizers have an impact on mamey production.

There are four treatment (a=4); three types of fertilizer and the control. Each treatment has four replicates (n=4). The number of mameys produced is given in the table below.

a. (10 points)Using these data a 1-Way ANOVA table. Use MATLAB or your program of choice to calculate the p-value. Would you reject the null hypothesis?

F ₁ : 1, 2, 6, 11

F ₂ : 2, 4, 2, 4

F ₃ : 12, 4, 2, 6

With: 3, 3, 1, 1

b. (10 points)What is the proportion of explained variance for this treatment?
