Capital University, a mid-size university located in a capital city has approximately 10,000 students studying in four departments. While the University’s goal is not to make a profit, it is also important that the University does not operate at a loss. The only source of revenue is tuition and government grants. The government gives the University $14,000 a year for each full-time student. Faculty: Arts Science Engineering Business Number of Courses 120 200 150 150 Number of Students 4,800 2,000...

a) You are studying a population of aphids with an initial
population size of 500. During a one-month period, you observe 40
births and 15 deaths in the population. Estimate the value of r for
that month, and predict the population size in three months (from
the initial population size). Remember that r is the per capita
rate of population increase. (Assume exponential population
growth).

Problem #6: The grade point averages (GPAs) of a large population of college students are approximately normally distributed with mean 2.5 and standard deviation 0.80. (a) What proportion of the students will possess a GPA greater than 3.0? (b) Suppose that 10 students are randomly selected from the student body. What is the probability that atmost 4 among 10 will possess a GPA greater than 3.0? (c) What would be the maximum GPA so that only 10% of the students...

Suppose that a very large population of students has taken this same test on the internet. Their mean score was 7 and their population standard deviation was 4. Assume that there are 49 students in our statistics class and that these students can be thought of as a random sample from the same large population of students who took the statistics quiz online. Suppose that the mean quiz score for our class is 9. Now imagine that we draw many...

Questions 1-4: There are 1300 students taking an introductory class, and we'd like to know the proportion of these students that are freshmen. We draw a random sample of size 100. We ask each of these 100 students whether they are freshmen. We then find the proportion in this sample that are freshmen. 4. What is the statistic?: Oa. The 1300 total students enrolled Ob. The 100 students selected Oc. The proportion of students in the sample that are freshmen....

A simple random sample of size n = 41 is obtained from a population with u = 67 and o = 17. (a) What must be true regarding the distribution of the population in order to use the normal model to compute probabilities involving the sample mean? Assuming that this condition is true, describe the sampling distribution of x. (b) Assuming the normal model can be used, determine P«<71.4). (c) Assuming the normal model can be used, determine Plă 269.3).
