Question 2 1 pts
Which of the following is the best description of Homogeneity of Variance?
It indicates that there is no difference between samples, therefore the null hypothesis will be retained.
The two samples must be selected from a single population to ensure they vary in the same way.
0
The populations represented in the samples (two) vary similarly.
O The variance of the samples, once calculated should be the same.

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
