1. A botanist wants to determine how soil salinity affects plant growth. He conducts an experiment by growing the same species of plant in three different concentrations of salt for a month and measures each plant's height in inches. His results can be seen in the table below: 15% salt 5% salt 8 10% salt 5 2 7 4 4 5 4 7 10 6 5 6 2 3 a. State the null and alternative hypothesis b. Complete the ANOVA table Source Between (1 mark) (3 marks) Sum of Squares Df SS Mean Squares F 2 C. groups/Treatments Within Groups Can you compare the F critical value in the F distribution table and the F value in the ANOVA table?, and what is your conclusion?
