Sprouts again The students running the sprouts experiment

(Exercise 12) also kept track of the number of beans sprouted (out of 40) for each of the 36 dishes. Here are the partial boxplots of Sprouts plotted against Salinity and Temperature:

Adjusted # of Sprouts 30 20 20 10 0 4 8 12

An ANOVA table shows:

Salinity (ppm) Adjusted # of Sprouts 22.5 - 15.0 7.5 75 HH

An interaction plot shows:

HIH 32 34 36 Temperature (C)

A plot of residuals vs. predicted values shows:

a) State the hypotheses about the factors (both numerically and in words).

b) Perform the hypothesis tests and state your conclusions.
Be sure to check conditions.
