Question

This requires you to conduct a one-way analysis of variance.

Data are given to you on the “days on market” for a random sample of homes for sale by realtors using 5 different training programs that the realtors experienced. The 5 programs can be described as: computer-based course, campus training (on-site in a classroom), apprentice (work side-by-side with a mentor), field (solo field training), and self (a self-paced training course with books and coursework at home).

1. Present the null and alternative hypothesis for an experiment to determine if there are significant differences in the “days on market” for the realtors experiencing the different training programs.

2. Present the excel output for the one-way analysis of variance and state your decision (whether you reject or fail to reject the null) and conclusion (whether you have sufficient evidence for, or insufficient evidence for,….the alternative). Be sure to clearly state your F_computed (a.k.a. F-value) and P-value.

Answer 1

A)Null Hypothesis , H₀: There is no significant difference in the days on market for Realtors experiencing the 5 different programs (ie)

Alternative Hypothesis,H_a:There is significant difference in the days on market for Realtors experiencing the 5 different programs (ie)

B)

F value = 95.0069

p value = 1.394E-29

Since p value is less than .05 , we reject the null hypothesis and conclude that there is significant difference in the days on market for Realtors experiencing the 5 different programs
