Answer the below listed questions completely and in APA format to include a cover page. Part 2 should be
completed separately from the two questions/problems.
Question 1.

F-ratio
a. How many different populations are being considered in this analysis?
b. Fill in the ANOVA table with the missing values.
c. State the appropriate null and alternative hypotheses.
d. Based on the analysis of variance F-test, what conclusion should be reached regarding the null
hypothesis? Test using x-0.05.
Question 2.
The Promise Seed Co. was founded in Baltimore in 1876 by a 19 year-old with a passion for plants and animals
and a father willing to lend him $1000 of “seed money” to get started in business. Today, it is owned by Tim
Carlton Jr. One of Promise’s most demanded seeds are corn. Promise continues to increase production to meet
the growing demand. To this end, an experiment such as the one presented here is used to determine the
combination of fertilizer and seed type that that produces the largest number of kernels per ear.

a. Determine if there is interaction between the type of seed and the type of fertilizer. Use as significance
level of 0.05.
b. Given your findings in part a, determine if there is a difference in the average number of kernels per ear
among the seeds.
c. Repeat part b for the types of fertilizer. Use a significance of 0.05.
Part 2. (this should be done separately from the two problems listed above).
Do research on the internet and see what interesting facts you can find on F-statistic. Share with your
classmates an example of when the F-statistic would be a useful value in data analysis. Provide details of
what you would measure and how the F-statistic would be used.
