300
Step-by-step explanation:
To get from 120% to 100% you divide by 1.2 360/1.2=300 :)
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
Answer:
y=2x-2
Step-by-step explanation:
the slope is 2/1 so its 2x and the y intercept is -2 so its is y=2x-2
