write code in R Your supervisor responds to your email about the analysis, but your not sure that he read it. "Employee" "Ignore my previous email, I actually needed you to compare the control and treatment groups of the data I sent you to see if the treatment group has a higher mean than the control group. The researchers tell me that they aren't sure if the treatment impacted the variability of tensile strength, so don't assume equal variances. This needs to be on my desk by end of day." (Note: Your test should look for the difference between treatment control.) a) What is the difference between the observed difference of means and the expected difference of means under the assumed hypothesis? Save your answer in the variable q2.a b) What is the estimated standard error of this test? Save your answer in the variable q2.b
