Answer: a) 27.5, b) 5.33.
Step-by-step explanation:
Since we have given that
and n = 180
We need to calculate the sample mean and sample standard deviation.
So, the mean of the distribution of sample means is
The standard deviation of the distribution of sample means is
Hence, a) 27.5, b) 5.33.

(1,3)(3,5)
slope = (5-3) / (3-1) = 2/2 = 1
(3,5)(4,7)
slope = (7-5) / (4-3) = 2/1 = 2
False....they are not collinear because they have different slopes and do not lie on the same line
<span>You can select from any of the 8 on the first day, leaving 7 to choose from on the second day, leaving 6 for the third. So, 8 x 7 x 6 x 5 x 4 x 3 x 2 or 8! That's 8factorial, so multiply those out or use a calculator to get 8! and that is your answer.</span>
