Instructions

Perform the tasks and answer the questions using Python code $($Jupyter notebook$).$ Display results when applicable. Take screenshots of your work and paste them.

To start performing each task, import the Numpy library and give it an appropriate alias name. Find the version of the Numpy package on your system.

Task $1$

Create a Numpy array of $3*3$ dimension with values ranging from $9$ to $17.$

Hint: Use the arange$()$ and reshape$()$ functions available in Numpy.

Task $2$

Create a Numpy array holding values that are multiples of $5$ starting from $5$ to $100.$ Print this array in reverse order using a single statement.

Task $3$

Create an array of the height of students given below. Using aggregate functions, calculate the minimum height, maximum height, average height and standard deviation. Print the output up to a maximum of two decimal places.

Students$$ height: $5\mathrm{.}8,5\mathrm{.}6,6\mathrm{.}1,5\mathrm{.}9,5\mathrm{.}5,5\mathrm{.}7,5\mathrm{.}6,5\mathrm{.}9,6\mathrm{.}2.$

Task $4$

The overall years of experience of $12$ directors are given below:

$22,21,18,23,19,20,22,21,20,19,23,22$

Their years of experience in previous companies are given below in respective order:

$16,12,15,20,10,15,20,17,18,12,14,10$

i$)$ Create an array that holds only the experience of directors in their current company.

ii$)$ Find the minimum, maximum and average years of experience of the directors in their current company.

iii$)$ Create an array that contains years of experience of directors that are greater than $5$ years. How many directors have more than $5$ years of experience?

Task $5$

Create two arrays of dimension $3*3(3*3$ matrix$)$ using the two lists of numbers given below:

$3,3,3,2,2,2,1,1,1$

$1,1,1,2,2,2,3,3,3$

Find the product of the two matrices.
