40 Perfect SAT scores. It is possible to score higher than 1600 on the combined mathematics and reading por- tions of the SAT, but scores 1600 and above are reported as 1600. The distribution of SAT scores (combining mathematics and reading) in 2014 was close to Normal with mean 1010 and standard deviation 218. What pro- portion of SAT scores for these two parts were reported as 1600? (That is, what proportion of SAT scores were actually higher than 1600?)

The percentile is just the cumulative propor- tion stated as a percent: the percent of all values of the variable that were lower than this one. The upper arm approximately lengths of females in the United States are Normal with mean 35.8 cm and standard deviation 2.1 cm, and those for males are approximately Normal with mean 39.1 cm and standard deviation 2.3 cm. 3.39 (a) Cecile, a 73-year-old female in the United States, has an upper arm length of 33.9 cm.
