Question

For testing the difference between the two population means using paired data, we set the test of hypotheses H? : ?? ? ?? = 0, H? : ?? ? ?? ? 0 and use the following values: n? = n? = n = 10, d? = 0.3, s²d = 0.16, ? = 0.1 . Assume that sampling has been undertaken from a normal population. 1. The observed statistic is 2. The critical value that characterizes the critical region of the test is : t? = 3. The observed statistic a. falls in the critical region b. doesn't fall in the critical region (enter a or b ) 4. Use the table to find the closest lower and upper bounds of the p-value. < p-value < 5. A 99% confidence interval for the true mean difference would be in the form (complete the missing numbers with 3 decimals) Confidence interval = ± t0 . ( ) 6. Select the correct conclusion. c. There is a significant difference between the two population means. d. We cannot conclude that there is a significant difference between the two population means. (enter c or d)

          For testing the difference between the two population means using paired data, we set the test of hypotheses
H? : ?? ? ?? = 0,	H? : ?? ? ?? ? 0
and use the following values:
n? = n? = n = 10, d? = 0.3, s²d = 0.16, ? = 0.1 .
Assume that sampling has been undertaken from a normal population.
1. The observed statistic is

2. The critical value that characterizes the critical region of the test is :

t? =

3. The observed statistic
a. falls in the critical region
b. doesn't fall in the critical region
(enter a or b )

4. Use the table to find the closest lower and upper bounds of the p-value.

< p-value <

5. A 99% confidence interval for the true mean difference would be in the form (complete the missing numbers with 3 decimals)
Confidence interval =	± t0 . (	)

6. Select the correct conclusion.
c. There is a significant difference between the two population means.
d. We cannot conclude that there is a significant difference between the two population means.
