The 2020 Sabah state election took place on 26 September 2020. The collected data is tabulated in Table Q6 below. It shows the detected COVID-19 cases nationwide and in Selangor state in Malaysia after the election. The cases in Sabah have contributed significantly to the increase in Malaysia COVID-19 cases during this period. We want to know whether cases in Selangor have contributed significantly to the whole COVID-19 cases in the country or not in given period. (refer to the uploaded image) i. Determine the regression line equation from the given data. ii. Calculate the coefficient of Pearson correlation from the given data.ii. Conclude the correlation between COVID-19 case data collected for daily new COVID-19 case in Malaysia and Selangor State. From the correlation, do you think the cases in Selangor strongly affect the number of COVID-19 cases in the country in the given 10 days? Please justify your answer.
Answer: A professor wishes to study the daily recoveries from COVID-19 during four consecutive days in two countries, UG and OM. Data for Country UG = {3,8, 10, 6} and Country OM = {8,9, 10, 6} were of collected. Which country had more variable COVID-19 recoveries? Select one: O a. Country with more variations in recoveries from COVID-19 is UG. O b. Both countries UG and OM have same variations in recoveries from COVID-19. OC. Country with more variations in recoveries from COVID-19 is OM. O d. It is not possible to determine which country had more variations in recoveries from COVID-19.
Due to the alarming cases of Covid-19, a researcher wanted to study the characteristics of the patients in NCR infected by the virus. Lilliefors, a researcher, considered the following variables: M: age bracket (0-19, 20-39, 40-59, 60 and above) N: last country visited in the past 3 months O: number of days quarantined after manifestation of symptoms P: current status of the patient (mild, moderate, severe) 6. To answer the objective of the study, Lilliefors used different data collection methods. First, she gathered information about the variables of interest by letting the patients answer a self-administered questionnaire. Second, to supplement the data she gathered, she collected the sociodemographic profile of the patients using the data from the Department of Health. The methods of data collection used by Lilliefors are ________. A. objective and subjective, respectively B. subjective and objective, respectively C. objective and use of existing records, respectively…
Every Saturday, The Free Press, Mankato, Minnesota's daily newspaper, reports the number of new COVID-19 cases for the previous four weeks in the nine counties of south-central Minnesota. The data source is the Minnesota Department of Health. At α = .05, are the new COVID-19 cases each week independent of the patients' county of residence? Use your analysis of the South-Central MN COVID-19 Cases 8.14-9,10 data to answer the following questions. State the hypotheses and critical value for a chi-square test for independence. Perform the chi-square test for independence. Are the results reliable based on Cochran's Rule? Explain your reasoning. Report the chi-square test statistic, degrees of freedom, and p-value. Based on your findings, do you reject or fail to reject the null hypothesis? Explain the reasons for your decision. Study your analysis and interpret what its output reveals. Be specific about the relationship between the weekly COVID-19 data and the 9-county region. New…
4. Due to the alarming cases of Covid-19, a researcher wanted to study the characteristics of the patients in NCR infected by the virus. Lilliefors, a researcher, considered the following variables: M: age bracket (0-19, 20-39, 40-59, 60 and above) N: last country visited in the past 3 months what is variable M and N? M: Qualitative or Quantitative? N: Qualitative or Quantitative?
The COVID-19 (coronavirus) mortality rate of a country is defined as the ratio of the number of deaths due to COVID-19 divided by the number of (confirmed) cases of COVID-19 in that country. Suppose we want to investigate if there is any difference between the COVID-19 mortality rate in the US and the UK. On April 18, 2020, out of a sample of 671,493 cases of COVID-19 in the US, there was 33,288 deaths; and out of a sample of 109,754 cases of COVID-19 in the UK, there was 14,606 deaths. What is the 92% confidence interval in the true difference in the mortality rates between the two countries? What can you conclude about the difference in the mortality rates between the US and the UK? Justify your conclusions.

Katy is interested to understand the of herd immunity concept for Singapore's COVID-19 cases. She noted that 95% of adult population in Singapore's is fully vaccinated by the end of October 2021. She want to compare difference of COVID-19 death cases in Singapore's before Singapore's achieve herd immunity and after Singapore's achieve herd immunity. She collects the data of death cases in Singapore's two weeks in the early of October 2021 (to represent before herd immunity) and two weeks in the end of November 2021 (to represent after herd immunity). Assume the variable is approximately normally distributed. The data are presented as below. Before herd immunity After herd immunity 121 109 118 76 117 105 132 53 40 68 55 45 41 24 78 74 64 93 103 68 88 63 47 37 48 45 40 29 a) What test is appropriate to be used in this question?

Smoking History CoVID-19 Severity Low High Current 87 15 Former 43 9 Never 136 64 4.) One research question that could be posed using the available data: “Is there an advantage to being a Never smoker when it comes to CoVID-19 severity?” Essentially, we would like to know if the rate of High CoVID-19 severity is lower for Never smokers than it is for Current/Former smokers. Determine a method that would be appropriate for answering this research question. Using StatCrunch* and the available data, perform the statistical procedure deemed appropriate. Hint: In order to adequately answer this question, you will need to perform an additional statistical procedure a. What method did you use to answer the research question e.g., One-Sample t-Test for Means? b. Why did you select this particular method to answer the research question? c.

In a factorial experiment, Jessica studied the effects of vibration rates (Factor A) on seed germination of rice cultivars (Factor B). The experiment has 5 replication, each is handled by a research assistant. The experiment involves placing 100 seeds in a petri dish as one experimental unit and recording seed germination after applying the vibration treatments. The experiment is conducted as a Block Desing to eliminate errors due to variations in the accuracy of research assistants. What is the Block degrees of freedom (df)?

The basic reproductive number Ro for a disease serves as a measure of the intensity of the outbreak. This number quantifies the average number of people who will catch a disease from one contagious person if everyone in the population was susceptible, and an epidemic will occur if Ro > 1. Consider the spread of the same disease in two different populations, each with N members. Select all the factors applied to Population 2 that could explain the basic reproductive number in Population 1 being less than the basic reproductive number in in Population 2. Rejection of practices such as wearing a face-mask and social distancing. Education and resources to implement practices such as hand washing. Poor nutrition. Poverty-related crowding. The population has access to quality healthcare.
