Question
ldentify the choice that best completes the stale) 1. Two samples from the same population both have n = 10 scores with M-45. If the t statistic is computed for each sample, then what is the relationship between the two t values? a. The two t statistics will be identical. b. The sample with the larger variance will produce the larger t statistic. The sample with the smaller variance will produce the larger t statistic. c. d. There is no way to predict the relationship between the two t statistics 2. If other factors are held constant, which set of sample characteristics is most likely to produce a significant t statistic? c. n=100 with s2-100 d. n 100 with s2400 a. n 25 with s2-100 b. n 25 with s 400 3. A sample with a mean of M 40 and a variance of s?- 20 has an estimated standard error of 2 points. How many scores are in the sample? c. 10 d. 25 a. 4 b. 5 4. A sample of n -4 scores has SS 60. What is the variance for this sample? c. 16 d. 15 a. 30 b. 20 5. Which of the following samples will have the smallest value for the estimated standard error? n=25 with s2=100 c. n 100 with s 100 d. n 100 with s2 400 a, b. n 25 with s 400 6. A sample of n 4 scores has SS -48. What is the estimated standard error for the sample mean? c. 4 d. 16 a. b. 2 7. If other factors are held constant, which set of sample characteristics is most likely to reject a null hypothesis stating that ?-80? a. M-85 and small sample variance b. M-85 and large sample variance c. M-90 and small sample variance d. M-90 and large sample variance 8. A sample of n 25 scores has a mean of M 40 and a variance of s 100. What is the estimated standard error for the sample mean? a. 4 C. b. 2 d. 1Explanation / Answer
Please post 1 question per post, as we aren't allowed to answer assignment questions.
4. Variance in sample is given by the following formula:
= SS/N-1
= 60/4-1
= 20
b. is correct
