Human blood is classified by the presence or absence of three main antigens (A, B, and Rh). When a blood specimen is typed, the presence of the A and/or B antigen is indicated by listing the letter A and/or the letter B. If neither the A nor the B antigen is present, the letter O is used.The following table gives the percent of a certain country's population having each of the eight possible blood types in the sample space. Note that the presence or absence of the Rh antigen is indicated by the symbols + or −, respectively. Blood Types A+ A− B+ B− AB+ AB− O+ O− Percent 35.7 6.3 9.5 2.5 3.4 0.8 37.2 4.6 (a) What is the probability that a person selected randomly from the population has a blood type that is type O or Rh+?(b) What is the probability that a person selected randomly from the population has a blood type that contains the A antigen?(c) What is the probability that a person selected randomly from the population has a blood type that is type AB or Rh−?

The information is as follows: Month, Cases of Lyme Disease, Drowning Deaths: Month: January, February, March, April, May, June, July, August, September, October, November, December Cases of Lyme Disease: 3, 2, 2, 4, 5, 12, 22, 13, 6, 5, 4, 1 Drowning Deaths: 0, 1, 2, 1, 2, 9, 15, 5, 6, 3, 3, 1, 0 a) Compute the correlation coefficient for the data. b) Is there a significant linear relationship? c) Do you believe an increase in Lyme disease causes an increase in the number of drownings? d) A “lurking variable” is a variable that influences both of the variables (cases of Lyme disease and number of drownings) in a linear correlation study that is unknown or not accounted for in the study. Name one possible lurking variable that might cause the number of Lyme disease cases and drownings to be correlated.
15 Projected undernourished individuals. In 2020, The FAO, IFAD, UNICEF, WFP, and WHO published a brief .... NOURISH report on the state of food security and nutrition in the world. There were 687.8 million undernourished people in the world in 2019. One of the sections in the report shows the distribution of these people as shown in the following table: Region Africa Asia Northern America and Europe Oceania Latin America and the Caribbean Percentage of undernourished people (%) 36.4 55.4 0.9 0.4 6.9 a. Describe the variable measured in the table. b. These results were displayed in the form of a pie chart. Reconstruct the pie chart from the information given in the table. c. How many of the 687.8 million undernourished people in the world in 2019 were in Africa? d. As Africa has many third world countries, people might expect Africa to have the highest number of undernour- ished people in the world. Does the information in the pie chart, part b, support this contention? Explain why or…
