In the following choose the correct answer  The correlation coefficient for a sample of 10 students is 0.896.  After correlation coefficient of the transformed data.  a. should be greater than 0.896;  b. should be smaller than 0.896;  c. should be .896/2.5, because 2.5 cm = 1 inch;  d. should be the same. ....

Solution

2.

Yes, it will. A 95% confidence interval is more prone to include 0 in the interval, but it didn\'t (it says u1 > u2). Thus, a 90% interval also would not include 0, so it will also impky that u1 > u2. [ANSWER]

No, it wouldn\'t. A 90% CI is less prone to include 0 in the interval, yet, it did. Thus, a 95% confidence interval would definitely include 0.

Hence, it will not indicate that p1 and p2 are significantly different. [ANSWER]
