Question

Can you please do part (c) in Rstudio and show me your code? Thank you!

3.10. A product developer is investigating the tensile strength of a new synthetic fiber that wl be used to make cloth for men's shirts. Strength is usually affected by the percentage of cotton used in the blend of materials for the fiber. The engineer conducts a completely randomized experiment with five levels of cotton content and replicates the experiment five times. The data are shown in the following table Cotton Weight Percent 15 20 25 30 35 Observations 15 12 18 12 17 19 25 10 23 19 15 (a) Is there evidence to support the claim that cotton con tent affects the mean tensile strength? Use 0.05 (b) Use the Fisher LSD method to make comparisons between the pairs of means. What conclusions can you draw? (c) Analyze the residuals from this experiment and com ment on model adequacy
