The ability to determine the age of some individuals can be difficult if there are not quality government records of birth. Bone growth takes place at the growth plates at the end of long bones. Once all growth plates fuse, growth stops, and an individual is considered a biological adult. The age at which growth plates fuse for males is approximately normally distributed with a mean of 19 years and a standard deviation of 15.1 months. Complete parts (a) through (d). e this (a) What is the probability a male's growth plates fuse after age 21? The probability a male's growth plates fuse after age 21 is (Round to four decimal places as needed.)

A highschool teacher is interested in examining the math performance of one particular child, Mike, he has observed over several years. The highschool teacher has the mean and standard deviation for each year's maths test along with Mike's score on each test. Year Mean SD Mike's score 2018 90.5 5.1 96 2019 88.7 8.8 95 2020 69.5 3.4 78 Calculate the appropriate statistic to evaluate in which year Mike did his best in the math test relative to the other children tested over the years. To answer this question, we would need to compute a Q1. ABCD for each year, which would be Q2. ABCD for 2018, Q3. ABCD for 2019, and Q4. ABCD for 2020. This would mean that Mike's best math performance was in Q5. ABCD relative to the other children tested over the three years. In that year, he performed better than Q6. ABCD of the other children. Possible answers for Q4:A) -2.50B) -1.67C) 1.67D) 2.50 Possible answers for Q5:A) 2018B) 2019C) 2020D) Cannot tell…
