NASA excludes anyone under 5'2" in height and anyone over 6'3" from being an astronaut pilot (NASA 2004). In metric units, these values for the lower and upper height restrictions are 157.5cm and 190.5cm, respectively. The distribution of American adult heights within a sex and age group is reasonably well approximated by normal distributions as follows: 20-29 year old males: U = 177.6cm and 5=9.7 cm 20-29 year old females: H = 163.2 cm and 5= 10.1cm We want to answer the question: What fraction of the young female adults is eligible to be an astronaut pilot by these height constraints? Restated, we want to find Pr(females){157.5cm height 190.5cm}, (put the greater than and/or less than symbols in correct places). The standard normal deviate for the lower bound (round to 2 decimals) The standard normal deviate for the upper bound = (round to 2 decimals) One way to find the answer is 1-Pr(Z < lower bound upper bound) Using the Statistical Table B: The standard normal (Z) distribution, Pr(Z<157.5) = (report the exact number from the table, do not round) Pr(Z>190.5) = (report the exact number from the table, do not round) Thus, the fraction of young female adults that are eligible to be an astronaut pilot based on height alone is (report answer as a percentage to one decimal)

Permutations and Combinations

If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.

Counting Theory

The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
