On May 16, 2017, Verdun Hayes of Somerset, Great Britain set a new Guinness World Record: the oldest ever skydiver. The World War II veteran, who fought on the beaches of Normandy in 1944, set a new record when he skydived at age 101. Suppose the ages of all skydivers follow a normal distribution with mean 52.8 years and standard deviation 10.3 years. Based on this distribution, how old must a skydiver be to fall in the top 1.32% of the distribution? 75.033 75.669 72.242 29.931

LightCastle Partners, a Bangladeshi business management consultant, employs a large number of data analysts to analyze the data in a survey project. The time it takes for new data analysts to learn the analysis procedure is known to have a normal distribution with a mean of 99 minutes and a standard deviation of 14 minutes. a. What is the probability that the new data analysts will take more than 103 minutes to learn the analysis procedure? b. What is the probability that the new data analysts will take between 65 to 134 minutes to learn the analysis procedure? c. To maintain employee standars, LightCastle does not hire any analyst who fails to learn the process within a specified time. Therefore, what should be the specified time limit if they wish to retain at most 91.24% of new analysts?
According to College Board, the average out-of-state tuition for a four-year public college was $8,893 for the 2013-2014 academic year. There are a total of 629 four-year public institutions in the U.S. Assume that the standard deviation for the tuition for these colleges is $950. A random sample of 60 four-year public colleges was selected. What is the probability that the average tuition from this sample is less than $9,000?
