Suppose the ideal size of a particular university course is 150. It is known from historical data that on the average, only 30 % of those accepted for admission to this course will actually join. Assume that this year, the university accepts admission of 450 students for this course. Using a suitable approximation method, apply and compute the probability that at least 150 students will actually join the course.

23. Suppose a sample of n = 50 items is drawn from a population of manufactured products and the weight, X, of each item is recorded. Prior experience has shown that the weight has a probability distribution with 6 ounces and ơ-2.5 ounces. Which of the following is true about the sampling distribution of the sample mean if a sample of size 15 is selected? a) The mean of the sampling distribution is 6 ounces b) The standard deviation of...
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...
Concept 8. When calculating a 95% confidence interval for a population mean, which is the most important situation where use of the t distribution would be better than use of the normal distribution? Write the letter for the best choice. A. When the sample size is small. B. when the population standard deviation is unknown. C. when the sample standard deviation is unknown. D. When the population standard deviation is known. E. When the sample size is large. For 9...
For each question below select the best answer from those listed and give your reasoning. Your reasoning need only be a sentence or two. It is not enough to get the right answer, you must know why it is the right answer. Question 5 Fred's friend claimed that Canadians tend to be jerks.
