The compare is hat they both have the same y-intercept, the contrast is that tone line is positive and the other line is negative
Answer:
Step-by-step explanation:
If XY bisects DF at point E, then DE = EF.
Given DE = 2y and EF = 8y-3
2y = 8y-3
subtract 8y from both sides
2y-8y = 8y-8y-3
-6y = -3
y = 3/6
y = 1/2
y = 0.5
DF = DE+EF
DF= 2y+8y-3
DF = 10y - 3
DF = 10(0.5)-3
DF = 5-3
DF = 2
Answer:
Step-by-step explanation:
31.32
Yes because you are multiplying 3 z’s and also 3z’s
Answer:
The p value for this case would be given by:
For this case the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly higher than 0.1 and then Company B can reject the shipment
Step-by-step explanation:
Information provided
n=400 represent the random sample taken
X=59 represent number of defectives from the company B
estimated proportion of defectives from the company B
is the value to verify
represent the significance level
z would represent the statistic
represent the p value
Hypothesis to test
We want to verify if the true proportion of defectives is higher than 0.1 then the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
The statistic would be given by:
(1)
Replacing the info given we got:
The p value for this case would be given by:
For this case the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly higher than 0.1 and then Company B can reject the shipment
