3. Write a function named stdDev that computes the standard deviation of a set of numbers. The function takes the numbers in an array parameter and returns the standard deviation. The standard deviation of n numbers $x_1$, $x_2$, ... $x_n$ is the square root of \[ \left[ ((x_1 - m)^2 + (x_2 - m)^2 + \dots + (x_n - m)^2) / n \right] \] where $m$ is the average of the numbers. 4. Write a function named createIdPassword that takes a last name and a first name as parameters and returns an array containing an id and a password. The id is the first letter of the first name followed by the last name. The password is the first letter of the first name followed by the last letter of the first name followed by the first three letters of the last name followed by the length of the first name followed by the length of the last name. Both id and password are all upper case. For example if the first name is John and the last name is Maxwell then the id is JMAXWELL and the password is JNMAX47.

Type the correct answer in each box. Use numerals instead of words. A biologist is studying the effects of using a type of bacteria to clear drain pipes. She creates a simulation of a typical kitchen drain system and uses it regularly for three days before introducing the bacteria. She then carries out her simulation for another 15 days. The population of bacteria can be approximated using function $b$, where $d$ is the number of days since she started the experiment and $b(d)$ is the bacteria population in hundreds. $b(d) = \sqrt{5.2d - 15.6} + 2$ Use this information to complete the statement. The domain over which the bacteria population increases is $3$ $<d<$
