What would be an example of an impossible correlation coefficient? In other words, give a value of r that would lead you to suspect that the researcher made a mistake. The following data set was collected by Campus Life. They are investigating the possibility of arelations between students' time spent studying each week (in hours) and how much time they dedicateto campus life activities each week (in hours). In this table, each "ID" represents a single student.StudentX-Y - ActivitiesIDStudying1610235312441354781574789341210716Mean5.09.0Std. Dev2.55.0

In 2019, the United States Department of Education defined a "credit hour" as one hour per week of instruction, and two additional hours of work outside of class. So, for example, a 3 credit hour class should aim to have about 6 hours of outside-of-class work per week.Earlier this semester, I asked students how many hours they spent on the course outside of class time. A couple students provided helpful, but non-numeric, responses, so I omitted them from the data set. Below is a dotplot and summary statistics from the other responses: a)suppose we want to view this data as a sample of students from sections of Math 104. Then: n= xˉ= s= b)List at least one concern you might have about using this sample to do inference on the number of study hours for all students taking Math 104. c)Putting aside the concerns you raised in (b) the Professor is wondering if the sample demonstrates that the amount of work he assigns in the course is reasonable under the federal guidelines for a…
A paper in the Journal of Nervous and Mental Disorders reported the following data on the amount of dextroamphetamine excreted by a sample of children having organically related disorders and a sample of children with nonorganic disorders (dextroamphetamine is a drug commonly used to treat hyperkinetic children). Organic: 17.53, 20.60, 17.62, 28.93, 27.10 Nonorganic: 15.59, 14.76, 13.32, 12.45, 12.79 (Observations refer to percentage of recovery of the drug seven hours after its administration.) If we assume that the variances of the two groups of children are unequal, determine whether the true average percentages of recovery for the two conditions are equal at significance level 0.01
