error and the ANOVA t-test value on separate lines of your spreadsheet,
and use two decimal places for each value)
(d) Print out the resulting spreadsheet so that all of the information ﬁts onto
(e) Save the spreadsheet as: TROUT3
Now, write the answers to the following questions using your Excel printout:
1. What are the null hypothesis and the research hypothesis for the ANOVA
2. What is MS b on your Excel printout?
3. What is MS w on your Excel printout?
4. Compute = MS b /MS w using your calculator.
5. What is the critical value of F on your Excel printout?
6. What is the result of the ANOVA F-test?
7. What is the conclusion of the ANOVA F-test in plain English?
8. If the ANOVA F-test produced a signiﬁcant difference in the average weight
of the ﬁsh between the four types of crowding, what is the null hypothesis and
the research hypothesis for the ANOVA t-test comparing 350 ﬁsh per
container versus 500 ﬁsh per container?
9. What is the mean (average) weight for 350 ﬁsh on your Excel printout?
10. What is the mean (average) weight for 500 ﬁsh on your Excel printout?
11. What are the degrees of freedom (df) for the ANOVA t-test comparing 350
versus 500 ﬁsh?
12. What is the critical t value for this ANOVA t-test in Appendix E for these
degrees of freedom?
13. Compute the s.e. ANOVA using your calculator for 350 versus 500 ﬁsh.
14. Compute the ANOVA t-test value comparing 350 versus 500 ﬁsh using your
