def getAverage$($ mylist $)$:

$"""$

This function computes the average of a list of numbers.

Parameters

$----------$

mylist : list of int

One dimensional list of integers you will find the average of

Returns

$-------$

float

The average of the integers in the list

$"""$

pass

def getStandardDeviation$($ mylist $)$:

avg $=$ getAverage$($ mylist $)$

$"""$

This function computes the standard deviation in a list of numbers.

Parameters

$----------$

mylist : list of int

One dimensional list of integers you will find the standard deviation of

Returns

$-------$

float

The standard deviation of the integers in the list.

$"""$

pass

def getResults$($ data$\_$list, stat$\_$results $)$:

$"""$

This function creates a two$-$dimensional list stored in the parameter

stat$\_$results. Each sublist will contain two entries: the average and the

standard deviation for each corresponding sub$-$list in data$\_$list.

Parameters

$----------$

data$\_$list : list of int

Two dimensional list of integers you will find the average and standard

deviation of

stat$\_$results : list of float

Two dimensional list of floats which include averages and standard

deviations

Returns

$-------$

None

passTwo lists have been declared for you. values is a $2$D list of integer values. You can change the numbers in the values, but the solution provided below is for the default numbers provided in the notebook template. results is a $2$D list consisting of the average and sample standard deviation for each row in the values list. For example, the first row in results will have the average and sample standard deviation for the first row in values. To start, results is an empty list.

Complete the getAverage function that takes in a list of values as its parameter mylist. mylist is intended to be a row within a $2$D list of integers for this program. The function will compute the average and return it$.$ Most of this function has been completed for you.

Complete the getStandardDeviation function. It takes in a list of values as its parameter mylist. The function will need to call getAverage. The function will compute the standard deviation and return it$.$ If the length of the list is less than $2,$ return a $-999$ in it$.$ The formula for the sample standard deviation is:

$=1()21$

Complete the getResults function. It takes in a $2$D list of integers data$\_$list and an empty list stat$\_$results as its parameters. The function will go through each sub$-$list in data$\_$list and get the average and the standard deviation and append it to the stat$\_$results list. stat$\_$results will be a $2$D list with each sub$-$list including two elements: average and standard deviation for the corresponding sub$-$list in data$\_$list. See below for an example.
