Kong et al. (2012) studied mutation rates in Icelandic
children, specifically looking at mutations in single nucleotide polymorphisms
(SNPs). As part of this study, they also recorded the age (in years) of the
mother and the father. Part of their data are given below:
# of SNP Mutations
If you were to do a regression analysis of these data,
which would be the dependent variable and which would be the independent
variable? Explain your reasoning!
What is the regression equation for the relationship
between these two variables? For this part, I want you to show me the steps
you’d take to calculate the slope and the Y-intercept. You can check your
results using Excel or some other program, but you will not get full credit if
you simply give me the equation as generated by Excel or another program. (This
is all a fancy way of saying you need to calculate this part by hand!).
Determine whether the slope of this equation is
significantly different from zero, using a regression ANOVA approach.
