Questions 32-36 use the 'Plant Growth' dataset in R The PlantGrowth dataset in R contains information from an experiment to compare yields (as measured by dried weight of plants) obtained under a control and two different treatment conditions. Question 33 2 Points Using the PlantGrowth data set along with the variables 'weight' and 'group', test the hypothesis that applying a treatment affected the mean plant yield. State an appropriate null and alternative hypothesis for this investigation.

Test statistic = Blank 1 (Hint: you only need to report the test statistic value here.) Blank 1 Add your answer Question 35 1 Point By performing an appropriate hypothesis test, what can the researcher conclude based on the significance of the test statistic?
