Suppose students are given 5 assignments throughout the course of a semester. The number of assignments turned in on time, out of those 5 total, can be seen below. The instructor would like to know whether the likelihood of turning in any assignment on time is equivalent for all students, and independent for each assignment.

Suppose a statistician wishes to test whether a large number of observations Xi follows an exponential distribution with parameter A = 1. He wishes to test this hypothesis exactly, and intends that if the observations follow an exponential distribution with a different parameter the test should reject the null hypothesis given sufficiently many observations. In addition, he wants to have a numeric statistic that he could report and does...

python 3 question Project Description Electronic gradebooks are used by instructors to store grades on individual assignments and to calculate students’ overall grades. Perhaps your instructor uses gradebook software to keep track of your grades. Some instructors like to calculate grades based on what is sometimes called a “total points” system. This is the simplest way to calculate grades. A student’s grade is the sum of the points earned on all assignments divided by the sum of the points available...

My Ask You C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within & hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here...

1. A hypothetical investigation on rider satisfaction with a particular public transit system serving commuting residents of British California (BC) and Prince Edward’s County (PEC) offers some interesting findings. The proportion of commuters from BC that indicated low satisfaction with the transit system’s service in the 2018 calendar year was 65 percent, and the proportion from PEC was 70 percent. These point estimates were based on samples of 5,380 BC commuters and 6,810 PEC commuters, whose system-using commuters number in...
