Answer:
(
1.17
3
, 4.6
)
Step-by-step explanation:
Use the Pythagorean Theorem OR the distance formula (they are based upon the same principles).
The x-component of this distance is the distance from -7 to +9, which is 16. If you're unsure of why, graph a number line, plot -7 and +9 and then count the number of scale divisions between the two.
The y-comp is the distance from 2 to 2, which is zero.
Thus, the distance between the two points is sqrt(16^2+0^2), or 16.
The minitab report isn't given.
Answer:
H0 : μ = 2 um
H1 : μ ≠ 2 um
Step-by-step explanation:
The mean surface roughness of coated interior pipe is given as 2um.
This refers to the population mean, μ = 2 um
Therefore, the null hypothesis which usually aligns with the population mean value will be stated as :
H0 : μ = 2 um
The alternative hypothesis is used to test the claim that the mean surface roughness is different from 2 ; hence no direction is given, this is thus a 2 - tailed test
H1 : μ ≠ 2 um
