24. Assuming that other factors are held constant, which of the following would tend to increase the likelihood of rejecting the null hypothesis? a. Decrease the sample size b. Increase the sample mean difference c. Increase the sample variance d. None of the other 3 options would increase the likelihood
25 por QUESTION 4 Assuming that other factors are held constant, which of the following sets of data is most likely to produce a statistically significant value for the repeated measures t statistici n 15 and MD-2 On-15 and MD - 4 On - 30 and MD - 2 On - 30 and MD - 4 25 QUESTION 5 For which of the following situations would a repeated-measures research design be appropriate? comparing mathematical skills for girls versus boys at...
answer all please In an analysis of variance, the MS between and MS within represent the means of the squared variability between and within conditions. True • False QUESTION 14 If an analysis of variance produces SS between 30 and MS between 10, then the ANOVA is comparing three treatment conditions. True False QUESTION 15 Compared to an independent measures design a repeated measures study is more likely to find a statistically significant effect because it reduces the contribution of...

If other factors are held constant, which of the following sets of data is most likely to produce a significant value for the repeated-measures t statistic? n = 15 and SS = 10 for the difference scores n = 15 and SS = 100 for the difference scores n = 30 and SS = 10 for the difference scores n = 30 and SS = 100 for the difference scores
To An independent-measures t hypothesis test is appropriate when the value for a is known a. b. the mean for a treated group of subjects is compared to a known population mean C. one sample is used to test a hypothesis about one population P there are two separate samples containing different subjects 17. One sample of n 5 scores has a variance of s 10 and a second sample of n= 10 scores has s pooled variance is computed...
I want to ensure I am understanding this question fully Amath teacher claims that she has developed a review course that increases the scores of students on the math portion of a college entrance exam. Based on data from the administrator of the exam, scores are normally distributed with p=512. The teacher obtains a random sample of 2200 students, puts them through the review class, and finds that the mean math score of the 2200 students is 518 with a...

Are my answers correct? 2. Gravetter/Wallnau/Forzano, Essentials - Chapter 10 - End-of-chapter question 6 Two separate samples receive different treatments. After treatment, the first sample has n = 6 with SS = 236, and the second has n = 12 with SS = 340. The pooled variance for the two samples is 36.00 . Compute the estimated standard error for the sample mean difference. Estimated S(M1 - M2) = 3.00 If the sample mean difference is 7 points, is this...
