I would say that the graph shows a positive association since both the numbers go up. A liner association would be more straight, (2,18) would be the correct coordinates of the outlier and there is definitely an association I would say.
Hope this helps! (:
Answer:
I think the answer is 24 blue doors.
Step-by-step explanation:
If you take 84 and divide it by 4 you get 21. 21x4=84 So I believe the answer is 24. Hope this helps!

Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 12
For the alternative hypothesis,
µ < 12
Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = population standard deviation
n = number of samples
From the information given,
µ = 12 minutes
x = 8 minutes
σ = 12 minutes
n = 36
z = (8 - 12)/(12/√36) = - 4/2 = - 2
Test statistic = - 2
