Answer:
(1) Correct option is B.
(2) Correct option is C.
Step-by-step explanation:
The information provided is:

The (1 - <em>α</em>)% confidence interval for the difference between two mean is:

The critical value of <em>t</em> is:

degrees of freedom 

Compute the 95% confidence interval for the difference between two mean as follows:

Thus, the 95% confidence interval, (2.14, 3.86) implies that the true mean difference value is contained in this interval with probability 0.95.
Correct option is B.
The null value of the difference between means is 0.
As the value 0 is not in the interval this implies that there is a difference between the two means, concluding that priming does have an effect on scores.
Correct option is C.
There are a few other ways to answer this but one way i know is 5x + 15
Step-by-step explanation:
There are 20 chips in total.
P(red) = 8/20 = 2/5
P(not green) = 16/20 = 4/5
P(yellow or green) = 9/20
Answer: B
Step-by-step explanation:
It is one sided test of R-squared being zero versus being greater than zero.
These are the steps of the test.
1. State the null and alternative hypothesis: ...
2. Compute the test statistic: ...
3. Find a (1 - 0.05)×100% confidence interval for the test statistic. ...
4. Decide whether to accept or reject the null hypothesis: 5.991 ∉ [0, 2.28], so reject H 0 .
5. Determine the p-value.
