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.

Answer:
2.30/7.5
Step-by-step explanation:
4.30-2=2:30
2.5-10=7.5
Answer:
Replace l with 110 and w with 120
P = 2(110) + 2(120)
P = 220 + 240
P = 460 feet
