between these two variables at α = .05?
(i) Find r. (Give your answer correct to three decimal
places.)

For each variable of interest, do the following: 1. Find the mean, five-number summary, range, variance, and standard deviation. Display these numbers in a format that is easy to understand. 2. For each variable of interest, use its five-number summary to construct a boxplot. Each boxplot must be constructed horizontally, and must be accompanied by a brief descriptive paragraph that assesses whether the data appear to be symmetrical, left-skewed, or right-skewed. Construct a 95% confidence interval for the mean μ...

Conduct a formal hypothesis test of the claim that the mean longevity is less than 57 days. Test at significance α=0.05. Your written summary of this test must include the following: Your null and alternate hypotheses in the proper format. The type of distribution you used to construct the interval (t or normal). The P-value and its logical relationship to α (≤ or >). Your decision regarding the null hypothesis: reject or fail to reject. A statement regarding the sufficiency/insufficiency...
For each variable of interest – Percent Time Asleep and Longevity – create a grouped frequency histogram. For each histogram, use a class width of 10; use a lower limit of 0 for Percent Time Asleep and 15 for Longevity. Each histogram must include an informative title, along with correct labels for both axes. For each histogram, include a paragraph that answers each of the following questions: Is the histogram symmetric, skewed to the left, or skewed to the right?...

The ExceptionLab class provided: – Creates an array of 100 elements and fills it with random numbers from 1 to 100. – It asks the user for an index value between 0 and 99. – Prints the element at that position. – If a number > 99 is entered by the user, the class will abort with an ArrayIndexOutOfBoundsException • Modify the ExceptionLab: – Add a try-catch clause which intercepts the ArrayIndexOutOfBounds and prints the message: Index value cannot be...
2.29 The following is the C codes and the translated MIPS codes. Assume that the C-level integers t1 and a0 are held in register $t1 and $a0, and $s0 holds the base address of the integer MemArray. void foo () { int MemArray[100] = { 96, 98, 63, 69, 42, 27, 16, 6, 47, 74, 44, 33, 76, 7, 88, 33, 80, 86, 86, 64, 17, 67, 60, 51, 2, 61, 93, 87, 49, 98, 24, 98, 30, 65, 2,...
Problem #1: Consider the below matrix A, which you can copy and paste directly into Matlab. The matrix contains 3 columns. The first column consists of Test #1 marks, the second column is Test # 2 marks, and the third column is final exam marks for a large linear algebra course. Each row represents a particular student.A = [36 45 75 81 59 73 77 73 73 65 72 78 65 55 83 73 57 78 84 31 60 83...
Problem 4: Variables that may affect Grades The data set contains a random sample of STAT 250 Final Exam Scores out of 80 points. For each individual sampled, the time (in hours per week) that the student spent participating in a GMU club or sport and working for pay outside of GMU was recorded. Values of 0 indicate the students either does not participate in a club or sport or does not work a job for pay. The goal of...
