A study is tо be dоne tо compаre mаth аchievement in the two different middle schools in a certain city. A random sample of middle school students at North Middle School is chosen and their math achievement scores recorded. A random sample of middle school students at South Middle School is chosen their scores recorded. The data is provided below. Assume that the data meets the conditions to calculate a confidence interval. North: 45 50 60 63 52 57 51 44 55 57 South: 48 62 73 70 58 64 58 42 69 62 1. Are these considered dependent or independent populations? [dep] 2. What is the point estimate of the difference in the mean math achievement scores of students at North and South Middle Schools? [point] 3. We are 95% confident that the difference in the mean math achievement scores at North and South Middle school is between [lower] and [upper]. 4. Because the interval [is] we [conclude].
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].
