Albert is interested to understand the of herd immunity concept for Japan's COVID-19 cases. She noted that 95%of adult population in Japan is fully vaccinated by the end of October 2021. She want to compare difference ofCOVID-19 death cases in Japan before Japan achieve herd immunity and after Japan achieve herd immunity. Shecollects the data of death cases in Japan two weeks in the early of October 2021 (to represent before herdimmunity) and two weeks in the end of November 2021 (to represent after herd immunity). Assume the variableis approximately normally distributed. The data are presented as below.Before herd immunityAfter herd immunity121109118761171051325340685545412478746493103688863473748454029a) What test is appropriate to be used in this question? State why.b) Find sample mean and sample standard deviation of the above data.c) Can Albert concluded that the before herd immunity death cases is lower than the after herd immunitydeath cases. Test the claim at a = 0.10.d) Find 98% confidence interval of the difference in means.

Studies are being done by different pharmaceutical companies in their search for the COVID-19 vaccine. Suppose that "Goodbye COVID-19." a possible candidate for the vaccine is under study. This is given to patients admitted to different Philippine hospitals diagnosed with COVID-19. Researchers are interested in getting the mean length of days patients are in quarantine facility before they are cleared of the virus. They started giving the vaccine to two different sets of 50 patients from the onset of their illness until they are cured. The data collected was submitted to the Department of Science and Technology for evaluation. In this study, what is the parameter? a. two different sets of 50 COVID-19 patients b. number of patients with COVID-19 c. total number of hospitals admitting COVID-19 patients d. mean length of days patients under study are in quarantine facility
you randomly select 15 apple tree locations and 15 citrus tree locations from different forests. Each location is 1000 m² in size. Now you randomly create 10 zones within each forest (300 total) and measure plant biomass in each for three years (900 being the final tally) determine the population of interest, the dependent variable, the independent variable, and if the independent variable is being observed or controlled/manipulated, and number of replicates pseudoreplicates.
UCLA conducted a survey of more than 263,000 college freshmen from 385 colleges in fall 2005. The results of students' expected majors by gender were reported in The Chronicle of Higher Education (2/2/2006).

The article “State and Federal Data on COVID-19 Testing Don’t Match Up” by Meyer and Madrigal in May 2020 stated that Florida had reported conducting 700,000 coronavirus tests, yet the Centers for Disease Control and Prevention reported Florida had conducted 919,000. The difference between these reports is 219,000 tests. What is the difference between the number of tests Florida reported administering and the number the CDC reported the state-administered as a percent of the number of tests reported by Florida? Round your answer to the nearest hundredth of a percent.
Suppose that a study was conducted to determine if there is a significant difference in the average temperature of individuals before and after COVID-19 boosters were given. The temperatures of a sample of individuals were obtained before the boosters were given. The following day, their temperatures were again measured. The table below shows the data in degrees Celsius. (10 points) Temperature before Temperature after one day. Determine If there is a significant difference in the average temperature of Individuals who were given boosters at 5% level of significance. Assume that the differences in the temperatures follow the normal distribution.
Two different blood pressure medicines are being compared to determine if the average reduction in blood pressure is the same for each medication. The goal of the study is to determine if the medications differ. Twenty men age 50-60 years old are selected for the study. Ten men are chosen at random to receive the first medication and the other 10 men receive the second medication. Each of the 20 men is monitored for one month to determine the change in blood pressure over that time. Minitab provides the 95% confidence interval for (mu1 - mu2) (2.63, 14.18) a. Interpret this 95% CI. b. What assumptions (be specific) are necessary to construct this CI?
AP Stats Free Res ponse - Period 6 Name Date Many people consider Fosco University every year for its large graduate programs (estimated over 7,500 students each year). Fos co University provides housing for 10% of the gradua te students on campus. The housing office thinks that the percentage of graduate students looking for campus housing may be more than 10%. The office decides to survey a random sa mple of graduate students, and 62 of the 481 respondents say that they are looking for housing on campus. (a) With the results of the survey, would you recommend that the Fosco U niversity consider increasing the amount of housing on campus for graduate students? Give the appropriate evidence/test to support your dlaim. Use a significance level of.05. (b) In addition to the 481 graduate students who completed the survey, an additional 19 students did not respond. If the 19 responded, would you change your recommendation? Explain and show work.
