Please help give more calculating details for solve this question. Thank you so much.

3.10. A product developer is investigating the tensile strength of a new synthetic fiber that will be used to make cloth for men's shirts.

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. (a) Is there evidence to support the claim that cotton content 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 comment on model adequacy
