Step-by-step explanation:

Given

Solving (a): The mean

This is calculated as:

So, we have:

Solving (b): The standard deviation

This is calculated as:

So, we have:

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
