The raw data gathered on a university campus from a survey of art degree majors and theirresidency status were as follows: α11 =67, a12 = 33, a13 = 22, a21 = 132, α22 = 78,a23 = 39, α31 = 31, a32 = 11, α33 = 4, α41 = 74, a42=75, a43 = 22The following contingency table was created based on the above data, where you will need tocalculate the grand total, the total for each row, and the total for each column on your own beforeanswering the question that appears after the table.Digital MediaDrawing/PaintingSculptureStudio ArtsTotalIn-State Students671323174Out-of-StateStudents33781175InternationalStudents223922TotalCalculate the probability that someone is a studio arts major AND an In-State student.

A college student is interested in whether presoaking time has an effect on cleanliness of clothing. He collects the dirty clothes from all of the people in his dorm and randomly assigns clothing to one of four presoak time conditions: 5 minutes, 10 minutes, 15 minutes, 20 minutes. He then asks members of another dorm to rate the cleanliness of the items (they don’t know which clothing got which soaking time). The data are presented below. C) Perform an LSD test and answer the questions that follow (SHOW ALL WORK!!! This can be on the same page as your other ANOVA hand work.

A healthcare provider monitors the number of CAT scans perfomed each month in each of its clinics. The most recent year of data for a particular clinics follows (the reported variable is the number of CAT scans each month expressed as the number of CAT scans per thousand members of the health plan): 2.31, 2.09, 2.36, 1.95, 1.98, 2.25, 2.16, 2.07, 1.88, 1.94, 1.97, 2.02. Find a two-sided 95% confidence interval for the standard deviation. What should you do to address any reservations about this confidence interval? Round your answers to two decimal places (e.g. 98.76).
We are interested in estimating the proportion of people that can identify Nebraska but not Vermont. In a class of 55 students, each student was requested to select a sample of 6 people, show each person a map of the US and ask the person to identify the states of Vermont and Nebraska. The following numbers are the counts that each student got, that is, each number is the count of people in the student sample of 6, that could identify Nebraska but not Vermont.3344010110020030002020001100002010000001000200000001010Note: You can cut and past these numbers into an excel spreadsheet to help you calculate the mean and the standard deviation and compute the confidence interval. If you have trouble pasting them, paste them to a text file first and then copy from there.When we collect all the students' data, we have a sample size of 6x55=330.Of the sample of 330 people, what proportion were able to locate Nebraska but not Vermont?

The ability of lizards to recognize their predators via tongue flicks can often mean life or death for lizards. Seventeen juvenile common lizards were exposed to the chemical cues of the viper snake. Their responses, in number of tongue flicks per 20 minutes, are presented below. 319, 676, 710, 455, 744, 200, 370, 200, 472, 336, 455, 642, 795, 795, 438, 540, 489 Assuming normal distribution, a) Find a 90% confidence interval for the mean number of tongue flicks per 20 minutes for all juvenile common lizards. Assume a population standard deviation of 190.0. Note: The sum of the data is 8636. Confidence interval: (, ). b) Which of the following is the correct interpretation for your answer in part (a)? A. We can be 90% confident that the mean number of tongue flicks per 20 minutes for this sample of 17 lizards lies in the interval B. There is a 90% chance that the mean number of tongue flicks per 20 minutes for all juvenile common lizards lies in the interval C. We can be 90% confident…
