C8. According to the Pew Research Center (2015), recent immigrants are better educated than earlier immigrants to the United States. The change was attributed to the availability of better education in each region or country of origin. The percentage of immigrants 25 years of age and older who completed at least high school is reported in this table for 1970 to 2013. Write a statement describing the change over time in the percentage who completed at least a high school degree. 1970 1980 1990 2000 2013 Mexico 14 17 26 30 48 Other Central/South America 57 53 60 66 Asia 75 72 75 82 84 48 68 81 87 95 Europe 36 48 52 58 72 Caribbean 81 91 88 85 85 Africa Source: Pew Research Center, Modern Immigration Wave Brings 59 Million to U.S., Driving Population Growth and Change Through 2065, 2015.

BMX racing is a sprint sport where races range from around 30 to 45 seconds depending on thelength of the track. Given races are over in such a short time, the start - commonly referred to asgate starts due to everyone lining up on a gate, are critical to success in the sport. A coach with aparticular interest in data analysis coaching an elite athlete records data at a local race track for thetime it takes their athlete to reach the bottom of the starting hill.The coach has found that the hill times for their athlete follow a normal distribution with mean 2.3seconds and standard deviation 0.02 seconds. (a) What hill time distinguishes the slowest 10% of hill times? (b) What is the probability that a randomly selected hill time is less than 2.27 seconds? (c) Let X be the number of hill times that are less than 2.27 seconds from 10 separate starts. Assuming the athlete is well rested between starts, what distribution might you consider X to follow. Justify your response by…
.A new, miracle diabetes drug that diminishes major symptoms of diabetes has been approved by the FDA. Health care professionals and researchers believe that the new drug will prolong lifespan of diabetes patients. If the population is in steady state and the incidence is constant, what will the effect of this new drug be on the prevalence of diabetes in the population? Explain.
