Question

4. You perform an experiment to determine if there is a correlation between fat intake (mg/day) and growth in jellyfish over 5 days (change in bell diameter, in cm). Perform a linear regression on the results shown in the table below (/5). Lipid Change in What is the R? value of your regression? intake bell diameter (mglday)(cm) 8.819.4What is the slope value (m) of your 9 19.3 regression? 2.260 6.1 8.6 13 8.8 7.2 10.4 6.2 6.2 5 18.5 What is the intercept value (y) of your 16.1 24.8 10.5 regression? Using your regression, how much growth 11in the bell would you expect in a jellyfish fed 15 mg fat/day for 5 days?

Answer 1

$Correlation~coefficient=0.9095 \\R^2=0.8272\\ Slope=2.0527\\ intercept=0.4185\\ Predicted~growth~at~15~mg~fat/day=0.4185+2.0527*15=31.209~cm$
