6. Suppose you conducted a drug trial on a group of animals and you hypothesized that the animals receiving the drug would show increased heart rates compared to those that did not receive the drug. You conduct the study and collect the data in the attached file, "HRprob.CSV". Upload this file to your computer and use the read.csv command in R to load this file for analysis. Next use the R table() command to create a cross-tabulation table for this drug trial. .(7 points total) (1) State appropriate hypotheses to test for whether drug treatment is independent of heart rate increase./ (2) Calculate and report the percent in each treatment group who had increased heart rate. (3) Use the R chisq.test command to conduct the Chi-Square hypothesis test and state an appropriate conclusion. Report the test statistic, p-value, and conclusion (use the 5% significance level)
