Answer:
Its not nonlinear
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Answer:
Angle 2: 110 degrees, 1 and 2 would have to be the same for the lines to be parallel
Angle 3: 70 degrees angle 3 would have to be the complement to angle 1, so 1+3=180 and 70*3=180, so 3=70 degrees
Angle 4: 70 degrees, 3 and 4 have to be the same opposite angles for the lines to be parallel
Answer:
The p value for this case would be given by:
Since the p value is lower than the significance level of 0.05 we have enough evidence to conclude that the true mean for the assembly time is significantly different from 40 minutes.
Step-by-step explanation:
Information provided
represent the sample mean for the assembly time
represent the sample deviation
sample size
represent the value to verify
represent the significance level
t would represent the statistic
represent the p value for the test
System of hypothesis
We want to conduct a hypothesis in order to see if the true mean is equal to 40 minutes or not, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
(1)
Replacing the info given we got:
The p value for this case would be given by:
Since the p value is lower than the significance level of 0.05 we have enough evidence to conclude that the true mean for the assembly time is significantly different from 40 minutes.
