MATH302 Week 2 Test 2 Critique

MATH302 Test 1 critique The week one test for MATH302 was a great assessment of the material covered for the week. I felt it was challenging in a way that made me go back and review some of the materials. I took it twice and in reviewing the questions I missed or partially missed I realized it was only a matter of not paying closer attention to my work.

Math302 Week 5 Test Critique Test 5 was challenging and really tested our knowledge of this week’s lessons. I took the test twice and was able to do better on my second attempt. In reviewing the test to see where I missed the 100% mark, I see that my response to question #18 was incorrect, in looking at this multiple times, I do not recognize an error. The grading feedback is not helpful as I correctly answered the question:

1. Question: The least squares regression line for a data set is yˆ=5+0.3x and the standard deviation of the residuals is 0.4. Does a case with the values x = 3.3, y = 7.2 qualify as an outlier? 2. Question: The least squares regression line for a data set is yˆ=5+0.3x and the standard deviation of the residuals is 0.52. Does a case with the values x = -1.59, y = 5.78 qualify as an outlier? 3. Question: The following data represent the weight of a child riding a bike and the rolling distance...

1. Question: A manager wishes to see if the time (in minutes) it takes for their workers to complete a certain task is faster if they are wearing earbuds. A random sample of 20 workers' times were collected before and after wearing earbuds. Test the claim that the time to complete the task will be faster, i.e. meaning has production increased, at a significance level of α = 0.01 For the context of this problem, µD = µbefore−µafter where the first data set represents before earbuds and the...

1. Question: A dishwasher has a mean life of 11.5 years with an estimated standard deviation of 1.5 years ("Appliance life expectancy," 2013). Assume the life of a dishwasher is normally distributed. Find the number of years that the bottom 10% of dishwasher would last. Round answer to 2 decimal places. 2. Question: The size of fish is very important to commercial fishing. A study conducted in 2012 found the length of Atlantic cod caught in nets in Karlskrona to have a mean of 47.8 cm and a s...
