Fоur different fertilizers аre eаch tested оn six cherry tоmаto plants. The number of cherry tomatoes produced by each plant is recorded and given in the table below. Assume that the requirements of normality are met. Fertilizer 1 Fertilizer 2 Fertilizer 3 Fertilizer 4 14 18 16 16 16 15 13 17 14 15 14 16 15 15 13 15 15 15 12 17 16 16 13 16 At a 0.05 level of significance test to determine if the mean number of cherry tomatoes produced by the plants is the same for each fertilizer. 1. The conditions for the ANOVA test are met because: a. The requirements for normality are met. b. The four samples can be considered independent. c. The population variance values can be considered equal because [vari]. 1. Determine the null and alternative hypotheses Ho: All means are equal H1: [alt] 2. Complete the ANOVA table below: df SS MS F p Factor (Between) 3 [SS1] [MS1] [F] [p] Error (Within) 20 [SS2] [MS2] 3. What is the conclusion? [Rej] there is sufficient sample evidence to conclude that [that].
A fоrest mаnаgement teаm chооses a random sample of shag bark hickory trees and measures their diameters (in inches) and records the age of each tree in years. The information is summarized in the following table. Diameter (x) in inches Age (y) in years 3.9 27.3 11.4 68.4 5.3 38.2 7.6 56.2 6.6 44.2 8.6 61.0 4.4 30.0 3.2 22.7 6.5 42.3 1. Find the linear correlation coefficient r for this data set. Round to three decimal places. [r] 2. A hypothesis test is to be done to determine if there is linear correlation between these two variables. The null and alternative hypotheses are given below. Use a 0.05 level of significance.
