Question

Can you write the function in python?

def remove_outliers(data, num_outliers):

# When analyzing data collected as a part of a science experiment
it

# may be desriable to remove the most extreme values before
performing

# other calculations. Complete this function which takes a list
of

# values and an non-negative integer, num_outliers, as its
parameters.

# The function should create a new copy of the list with the
num_outliers

# largest elements and the num_outliers smallest elements
removed.

# Then it should return teh new copy of the list as the function's
only

# result. The order of the elements in the returned list does not
have to

# match the order of the lemetns in the original list.

# input1: data (list)

# input2: num_outliers (int)

# output: list

It has to pass this test.

Answer #1

copy = data[:]

copy=sorted(copy)

copy=copy[num_outliers:len(data)-num_outliers]

return copy

Many standard statistical methods that you will study in Part II
of this book are intended for use with distributions that are
symmetric and have no outliers. These methods start with the mean
and standard deviation, x and s. For example,
standard methods would typically be used for the IQ and GPA data
here data215.dat.

answers to two decimal places.)

Machine Problem 3 - Linked List C++
For this assignment you will write a program that inserts 20
random integers from 0 to 100 in order in a linked list object. The
program will create another linked list, but with 15 random
integers from 0 – 100 in order. The program then will merge those
two ordered linked list into a single ordered list.
The function merge should receive references to each of the list
objects to be merged and...
