Set the random number Pythonlist to variable x and write the code according to the items below.
(1)Write a code to find the second largest element among List x Element.
(ex.x=[4,4,2,1]->2,x=[5,4,3,1]-4)4)
(2)Write a code to find elements that appear only once in a while.
(ex.x=[4,4,2,1]->[2,1],x=[5,4,3,1]=>[5,4,3,1])
(3)Write a code that generates a list of the frequency of elements for each element of Listx.
(ex.x=[4,4,2,1]->y=[2,2,2,1,1],x=[5,4,3,1]->y=[1,1,1,1])
(4)Write a code to find the value that comes to the center of the list in descending order among the listx members. (*If the number of lists is even, suggest the average value of the two values that come to the center.)
(ex.x=[4,4,2,1]->3=(4+2)/2,x=[5,4,2,1,0]->2)

Referring to the table, suppose the researcher wants to obtain a 95% confidence interval estimate for the mean number of physical therapy programs received by patients who had exactly two muscle injuries. The confidence interval estimate is:
A researcher would like to analyze the effect of muscle injury on the number of physical therapy intervention programs received. She takes a random sample of 4 patients. For these 4 patients, she finds out how many times each had a muscle injury and how many physical therapy intervention programs they received. These data are presented in the table below:
Patient Number of Muscle Injuries Number of Physical Therapy
Programs Received
1 1 4
2 2 6
3 1 3
4 0 1
The results of the simple linear regression are provided below.
Y= 1+2.5X; = 0.5, = 0.35355; 2-tailed p value = 0.0192 (testing B1)

An aircraft firm is considering three different alloys for use in the wing construction of a new airplane. Each alloy can be produced in four different thicknesses (1 = thinnest, 4 = thickest). Two test samples are constructed for each combination of alloy type and thickness, then each of the 24 test samples is subjected to a laboratory device the severely flexes it until failure occurs. For each test sample the number of flexes before failure is recorded, with the results shown in the Aircraft worksheet in the ANOVA HW data workbook on Moodle.
a) Use JMP to fit a two-way ANOVA to the data. Using alpha = 0.05 draw conclusions for the ANOVA. Make sure you state your conclusion in the context of the problem.
b) Does there appear to be a need to include the alloy type / thickness interaction term?
c) Use JMP to fit a two-way ANOVA with interaction to the data. Using alpha= 0.05 draw conclusions for the ANOVA. Make sure you state your conclusion in the context of the problem.
