Please answer the following questions

Mrs. Hedigan observes the number of students cheating on her tests. She records the number of weeks since school began (let's call this, "school week") and the number of students caught cheating on her tests in the table bEIOW- School Week if of Students caught Cheating a) Use the following grid to construct a scatterplot in which school week is the explanatory variable and cheating students is the response variable. Based on your graph, does a linear model seem appropriate? Justify your answer. b) Use the data to construct a least-squares regression line to predict number of cheaters from school week. c) Assume that all conditions for inference are met. Indicate the hypotheses appropriate to test whether there is a linear relationship between number of cheaters and school week. d) The test statistic for the appropriate test is t = 15.857. Do the data provide convincing statistical evidence that there is a linear relationship between number of cheaters and school week
