Your firm will base some expensive decisions on the results of your hypothesis test, so your boss wants to have a high standard
of evidence for rejecting the null hypothesis. What should you do? A. Throw out observations that look suspicious
B. Increase the significance level to 10%
C. Reduce the significance level to 1%
D. Keep the significance level the same but collect more data
D. Keep the significance level the same but collect more data
Step-by-step explanation:
The significance level is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. This significance level is usually established initially and does not need to be changed.
But, you can collect more data to gain a high standard of evidence for rejecting the null hypothesis. More data gives more evidence and leads to a result that is not attributed to chance, thus, proving that the result is statistically significant.
Have you learned slope yet? Pick two points from the graph and do x-y on the top and x-y on the bottom. That would give you your slope then you can graph it. For example (-2,-1) (-1,1) -2-(-1) -1-1 Then that would give you -1/-2 so technically -1/2<< this is what you graph
This question is not a good question to ask, it is confusing, and is to complex, In brainly you are supposed to post 1 question at a time not 2 in 1 3in 1 4 in 1 e.t.c.
Sorry i couldnt help you, if you were to post separate questions i would be able to
