I need this by 2 pm eastern time 10 multiple questions. 1. The independent-measures t test uses data from two separate samples to test a hypothesis about the mean difference between two populations. (Points: 1) True False 2. The F-max test is used to determine if the two population means are equal. (Points: 1) True False 3. The results from an independent-measures t hypothesis test are reported as ?t(24) = 3.85, p < .01, two tailed.? For this test, df = 24. (Points: 1) True False 4. If other factors are held constant, an increase in the sample variances will have very little influence on measures of effect size for an independent-measures study. (Points: 1) True False 5. One sample has a variance of s2 = 8 and a second sample has a variance of s2 = 10. If the two samples are exactly the same size (n1 = n2), then what is the pooled variance? (Points: 1) 9 18 cannot be determined without more information 6. When computing difference scores (D values) the sign of the difference (+ or -) is not important. You need to record only the size of the difference. (Points: 1) True False 7. For a repeated-measures study, a small variance for the difference scores indicates that the treatment had a consistent effect for all of the participants. (Points: 1) True False 8. In a repeated-measures study, a statistically significant mean difference guarantees that the measures of effect size will be moderate or large. (Points: 1) True False 9. Which of the following samples will produce the largest value for a t statistic? Assume each sample has n = 10 scores. (Points: 1) MD = 5 with SS = 20 MD = 10 with SS = 20 MD = 5 with SS = 40 MD = 10 with SS = 40 10. A sample of difference scores has a mean of MD = 5 with a variance of s2 = 100. If effect size is measured using Cohen?s d, what is the value of d? (Points: 1) d = 5/10 d = 5/100 cannot determine without knowing the sample size,Can anyone do the work by 2 pm easter or 2:30 pm,I need a refund, this work was done after deadline...need a refund.
