Answer:
I believe the slope would be -2
Step-by-step explanation:
The line goes <u>down 2</u> boxes and <u>over 1</u> box before it intersects with another point.  Knowing slope =  , we know that slope =
, we know that slope =  which is equal to -2.
 which is equal to -2.

Answer:
0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 17.39 ppm
Standard Deviation, σ = 4.25 ppm
Sample size = 11 
We are given that the distribution of printing speed is a bell shaped distribution that is a normal distribution.
Formula:  
 
  
P(printing speed of the sample is greater than 17.99 ppm.)  
P(x > 17.99)  

Calculating the value from the standard normal table we have,

Thus, 0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.
