Question

4. [15 pts] In an agricultural experiment, the effects of two fertilizers on the production of oranges were measured. Sixteen randomly selected plots of land were treated with fertilizer A, and 12 randomly selected plots were treated with fertilizer B. The number of pounds of harvested fruit was measured from each plot. Assume that the yields are approximately normally distributed. Find a 95% confidence interval for the difference between the mean yields for the two types of fertilizer. | | sample mean | sample variance | |---|---|---| | Fertilizer A | 457.31 | 1480.90 | | Fertilizer B | 394.17 | 526.88 |

Step 1

We are given the sample means and sample variances for both fertilizers. Let's denote them as follows: - For Fertilizer A: $\bar{x}_A = 457.31$, $s^2_A = 1480.90$, and $n_A = 16$ - For Fertilizer B: $\bar{x}_B = 394.17$, $s^2_B = 526.88$, and $n_B = 12$ Show more…
