### Problem 3 RStudio Must be able to put code where it ways # Insert R code below this line Two competing headache remedies claim to give fast-acting relief. An experiment was performed to compare the mean lengths of time required for bodily absorption of brand A and brand B headache remedies.

| | Mean time | s | Sample size N | |----:|----:|----:|----:| | Brand A | 21.8 min | 8.7 min | 12 | | Brand B | 18.9 min | 7.5 min | 12 | Past experience with the drug composition of the two remedies permits researchers to assume that both distributions are approximately normal. Compute the confidence interval for the difference of these two drugs, assuming a leve of confidence of 97 %.
