COMM 215 Data Analysis Project Winter 2021 b. Repeat all questions of part(a) for the variable Cumulative Number of Cases (Total per Million People). 5. For the variable Cumulative Number of Deaths - total per million people (Column H). a. Construct a Box-and-Whiskers plot to determine if there are extreme outliers (ie: use outer fences). Discuss your ndings. b. Repeat part (a) but use the variable Cumulative Number of Cases (Total) (Column C). 6. Determine if the WHO Regions (Column B) is independent of the Transmission Classications (Column K). 7. From March I. 2020 until May 3i. 2020. IOO random samples of size n = 30 were taken on the Deaths per million people in New Zealand. This sampling distribution was found to be approximately normally distributed with a mean = 0.34 deaths per million residents and a standard deviation of O.| | deaths per million people a. Given the above data. what is the probability that you, as researchers. will randomly select a small sample of 30 days with an average number of deaths per million exceeding 0.5 deaths per million? Test your hypothesis at the 90th and 95th percentiles. b. The same process was done in Australia (same time period 1' same number of samples 7 same sample size)I and the Australian average number of deaths per million was found to equal 0.3I with a standard deviation of 0.5. Repeat part (a) for Australia and comment in your report about the differences in the distributions between the two neighbouring countries (why are they so dierent?) 8. Create a scatter plot comparing the Cumulative Number of Deaths in the last 7 days (column I) to the Cumulative Number of Deaths in the last 24 hours (column J). a. Comment on the correlation (strength 7 direction) b. Repeat part (a) but use the variables in columns E & F 9. Construct a simple regression equation that describes the relationship (if any!) between the Cumulative Number of Deaths in the last 7 days (column I) to the Cumulative Number of Deaths in the last 24 hours (column J). a. What is the relationship? (ie: provide an equation) b. Is the relationship statistically signicant? How can you tell? c. Discuss the 95% condence interval of the model's slope. IO. Using the information in Question 9, discuss the following points in your report a. If on a given week (7 days), a nation reports a total of 2000 new deaths due to the COVID l9 virusI what is the expected value for the number of deaths over the next 24 hours for that nation? b. Calculate a 95% condence interval for the mean value of your dependent variable and discuss your ndings
