Studies of the size and range of wild animal populations often involve
tagging observed individual animals and recording how many times each
is caught in a trap (from which it is then released back into the wild).
The dataset presented in Table 3 consists of the numbers of times each
of n = 334 wood mice were caught in a particular trap (over a two-year
time period). The data are also provided in the Minitab file
wood-mice.mwx.

The geometric distribution with parameter p is a good model for these
data.
(i) What is the maximum likelihood estimator of p for a geometric
model?
(ii) What is the maximum likelihood estimate of p for the data in
Table 3? You are recommended to use Minitab to help you to
answer this part of the question.

They looked at 1125 men and 1413 women in the Framingham Osteoporosis Study, which is a cohort that began in 1971. The first examination in this study began between 1971 and 1975, with participants returning for an examination every 4 years. Based on results of questionnaires, the researchers were able to determine cola consumption on a weekly basis. Analysis of the results indicated that women who consumed at least one cola per day (on average) had a bone mineral density that was significantly lower at the femoral neck than those who consumed less than one cola per day. The researchers did not find this relation in men. (a)Why is this a cohort study? (b)What is the response variable in this study? What is the explanatory variable? (c)Is the response variable qualitative or quantitative?arrow_forward
- During the Covid crisis, there were lockdowns and working-from-home, whichmade collecting data on unemployment more challenging. Researchers fromHeriot Watt University conducted a survey of 1,000 individuals in the labour forceto assess rise in unemployment in September 2020. The object was to find outwhether the unemployment rate had risen above a benchmark proportion of 5per cent of the labour force in Scotland. Of the surveyed persons, 60 reportedbeing unemployed in the week prior to the survey.(i) Conduct a two-tailed test of whether unemployment rate during this periodwas 5 per cent. Set out your null and alternative hypotheses, significancelevel, test statistic, assumptions and sampling distribution clearly.

- Enlist the types of experimental designs. Provide the details regarding their validity and procedure by formulating tables.arrow_forwardA project was conducted with the objective of improving the wait time in a local hospital. The evaluation plan included waiting room time as one key waiting time process measure. Waiting room time was defined as the time elapsed between requesting that the patient be seated in the waiting room and the time he or she was called to be placed in an exam room. Initially, the target was set of 25 minutes. After implementing an improvement framework and process, the quality improvement team collected data on a sample of 355 patients. In this sample, the mean wait time was 23.05 minutes, with a standard deviation of 16.83 minutes. If you test the null hypothesis at the 0.01 level of significance, Is there evidence that the population mean wait time is less than 25 minutes?arrow_forwardA researcher conducts an experiment comparing two treatment conditions and wants to have 30 scores in each treatment condition.

- GMU uses a robot food delivery service which now has been utilized in the City of Fairfax. One of the potential benefits of this service is to help the busiest students eat breakfast. Research has shown that about 80% of college students skip breakfast due to busy schedules and other reasons. Initial data were collected from a random sample of 595 Mason students who utilize the robot food delivery service and are presented in StatCrunch.arrow_forwardAfter each government project is completed, the concerned department inspects the project and given a “pass” or “fail” rating. A pass rating is necessary before the appropriate contractor is given the final payment. A failed project must be reinspected until it passes the inspect. The reinspection is both costly and time-consuming. In order to deter failure, the government decided to publicize the inspection records of all contracts. A year after the web access was made public, two samples of records were randomly selected. One sample was selected from the pool of records before the web publication and one after. The proportion of projects that passed on the first inspection was noted for each sample. Test whether there is sufficient evidence to conclude that public web access to the inspection records has increased the proportion of projects that passed on the first inspection by more than 5 percentage points.

Justify your answer in each case. Do Left-Handers Die Earlier? According to a study published in the Journal of the American Public Health Association,lefthanded people do not die at an earlier age than right-handed people, contrary to the conclusion of a highly publicized report done 2 years earlier. The investigation involved a 6-year study of 3800 people in East Boston older than age 65.Researchers at Harvard University and the National Institute of Aging found that the “lefties” and “righties” died at exactly the same rate. “There was no difference, period,” said Dr. J. Guralnik, an epidemiologist at the institute and one of the coauthors of the report.arrow_forward
