- Repeat Example 5 when microphone A receives the sound 4 seconds before microphone B.1. Between the years 2011-2019, which year had the fewest global cases of measles reported? Between the years 2011-2019, which year saw the most global cases of measles reported? Between the years 2011-2019, which year saw the largest increase in global measles cases over the year before? 2. According to the CDC, the fatality rate for measles is 0.2% in the United States. However, in developing countries it is approximately 25%. According to the World Health Organization about 75% of measles cases occurred in developing countries in 2019. How many deaths from measles are likely to have resulted in developing countries? Round your answer to the nearest thousand. According to the CDC, 6% of people who contract measles also develop pneumonia. If there were 1,296 cases of the measles in the United States in 2019, how many people developed pneumonia? Round to the nearest whole person. By approximately what percentage (relative change) did measles decline between 2014-2015? Round…Suppose you roll a die until the first time you obtain an even number. Let X1 be the total number of times you roll a 1, and let X2 be the total number of times that you roll a 2. Use simulation in R to test if E[X1]=E[X2]. Include a screenshot of the RStudio approach. Hint: It is extremely unlikely that you will roll 30 times before getting the first even number, so you can safely assume that the first even roll occurs inside of 30 rolls. E[X1]=E[X2] or E[X1]≠E[X2]
- Individual A has a red die and B has a green die (both fair). If they each roll until they obtain five "doubles" (1-1,...,6-6), what is the pmf of X (= the total number of times a die is rolled)?

What percentage is likely to be infected in week 4 if N(3) = 8 and N'(3) = 1.2?7) (a) If you make α too big (e.g., α = 0.2 (you should never use α > 0.1)), what kind of error are you more likely to make (type I or type II)? Why? (b) If you make α too small (e.g., α = 0.0000000001), what kind of error are you more likely to make? Why?
