A company runs a competition where customers can win a prize by completing a quiz. The quiz consists of 31 multiple choice questions that can be answered by searching for information about the company on their website (similar to our Course Success Quiz). Each multiple choice question has 4 answers, of which only one is correct. Because customers could select an answer for each question without looking up the information on the page, the company will only select attempts at the quiz to raffle for a prize that are better or worse than 'just chance'. Suppose a customer gets 9 questions correct in the quiz. The [Select] hypothesis for a statistical test appropriate for this %. situation is p = [Select] The observed proportion of questions the customer got correct is [Select] with the null model, because it is [Select] the middle [Select] % of the null model generated data. There [Select] evidence that the customer did better or worse than 'just chance' when selecting the correct answers on the quiz.

Due to COVID-19, the quantity of local parcel deliveries by ADIX courier service has increased over the months. The company's data analyst claims that the current trend of the number of waiting days for local deliveries follows Poisson distribution 2 days. To verify the claim, he collects new data on the number of local parcel deliveries by the courier for the latest six weeks. The data collected and its associated Poisson probability are shown in Table 3. 1) Based on the new data, will the data distribution be the same as initially claimed by the analyst? 2) In your opinion, does the data provides a good fit to the distribution. Justify your answer.

Suppose next that we have even less knowledge of our patient, and we are only given the accuracy of the blood test and prevalence of the disease in our population. We are told that the blood test is 9# percent reliable, this means that the test will yield an accurate positive result in 90% of the cases where the disease is actually present. Gestational diabetes affects 1 percent of the population in our patient’s age group, and that our test has a false positive rate of 4 percent. Use your knowledge of Bayes’ Theorem and Conditional Probabilities to compute the following quantities based on the information given only in part 2: What is the probability of having the disease given that you tested negative? Comment on what you observe in the above computations. How does the prevalence of the disease affect whether the test can be trusted?

The population of children under 5 years in Whitefish, Montana on July 1 2015 was 2,350 with no population change reported for the next year. In that year, in a daycare of 150 children under 5 years in Whitefish, Montana, 50 of them develop Respiratory Syncytial Virus (RSV). During the next 3 months, 8 of the children with RSV died with 5 of them being reported to be associated with RSV infection. No other deaths were reported among children under 5 years in this town. The incidence of RSV would be [Select the option closest to your answer] A. 0.02% B. 2.2% C. 33.3% D. 3.3%

In 'Stat' World it is known that 10% of the entire population of 100 million people are infected with 'HALO' disease. 'HALO' has a range of outcomes that range from 'asthma' to 'reduced life span' to 'imminent death'. 'Stat World' has developed a screening to test for the 'HALO', and this test has an accuracy of 80% in identifying 'HALO'. 'Stat World' has also developed a 'HALO' treatment ('BLOCK') that has 90% rate of full cure if you have 'HALO'. However if you receive 'BLOCK' treatment and do not have 'HALO' disease you will be incurably infected with 'HALO'.   What is the probability that you have 'HALO' if you test positive for 'HALO'?   What is the probability that you have 'HALO' if you test negative for 'HALO'?   What is the probability that you are harmed by 'BLOCK' treatment if you tested positive for 'HALO'?   What is percentage of population that will be cured by 'BLOCK' if all positive 'HALO test results are treated with 'BLOCK'?         (e) What is percentage of…

It is believed that at least 60% of the residents in a certain area favor an annexation suit by a neighboring city. What conclusion would you draw if only 120 in a sample of 210 voters favor the suit? Use a 0.03 level of significance. Need solution like in the picture attached

Women athletes at the University of Colorado, Boulder, have a long-term graduation rate of 67%.  Over the past several years, a random sample of 38 women athletes at the school showed that 21 eventually graduated.  Does this indicate that the population proportion of women athletes who graduate from the University of Colorado, Boulder, is now less than 67%? Use α = 0.05 level of significance to test.
