Assignment Guidelines The following Assignment Guidelines are relevant for all the assignments in Parts 2 and 3 of the course. When you do a statistical test of a particular hypothesis, it is assumed you will state the following, if relevant: Model equation. Assumptions about the data, and comments about whether diagnostic graphs support those assumptions. Null and alternative hypotheses. ANOVA Table (if relevant) and p-value. 12 Statistical conclusion(s) (e.g., "We reject Ho and conclude H, that and 2 differ at the 5% significance level"). Interpretation of the statistical conclusions back to the original problem, using the original meaning of the response variable and any factors or covariates. For example, if comparing heights of two groups, "Female and male adults have different mean heights, with males being taller on average". Insects were reared in a laboratory at various temperatures. Their development times (in days) are given below. Of particular interest to the researcher is whether temperatures 16C and 20C have any difference in mean development time.

Analyse the experiment (i.e., do the overall test, the ANOVA) using R. Be sure to check the ANOVA assumptions. b. Test for significant differences between the 16C and 20C groups using a Tukey test. c. Write up the results as a brief research report, following the Assignment Guide- lines below.
