The the value of Mp fort these data? a. 4 data were obtalned from a re Subject 1st 2nd C. d. 20 B 15 6 10 9 17 2) A researcher conducts a research study compading two treatment conditione and study obtains 30 scores in each treatment. If the rused a experiment comparing two treatment conditions, a re d. cannot be design, then how many indviduals participated in the research shidyn b. 31 d. 41 For an would obtain design score(s) for each subject b. 2 If the null hypothesis is true, what value is expected on average for the t statistc? a. 0 C. 1.96 E) it a single sample study shows a significant difference 01, then you can be sure that a. the value of Cohen's d is large. b, the value of Cohen's d is small. C the value of Cohen's d is medium. d. A significant effect Which does not necessarily mean that the effect size will be large. of the following d values is considered medium a. .87 A researcher conducts a single obtains a t statistic of t b. 0.22 c. 0.51 d. 0.08 sample study with a sample of n = 16 participants and 2.65. Which of the following is the correct docision for a two- tailed test. a. Reject the null hypothesis with a=.05 but fail to reject with 01. b. Reject the null hypothesis with either a-.05 or a .01 c. Fail to reject the null hypothesis with either a .05 or a-01 d. cannot determine the correct decision without more information True or False H The formula used in repeated-measures t statistic is used with a matched-subjpcts design even though the design uses two separate samples. .One advantage of a repeated-measures design is that it typically requires fowor participants than an independent-measures design. Whencomputing-difference scores" (D values) the sign ofthe ditlerenoa(+or-)isnot t. You need to record only the size of the difference. To get a big effect size, you should increase N Power analysis are nducted before hypothesis testing begins. confidence intervals, there is a tradedi between precision and confidence.

Explanation / Answer

Dear student,

Since the first question is not quite readable so here b,c,d,e are solved.

b, Here , 30 individuals take part in the research.

c, Here, there will be 2 scores for each subject.

d, Here, the value of t-statistic is greater than 1.96 for the null hypothesis to be true.

e, If at alpha=0.01 there is a significant difference among two means than the cohen's d is large.

Please give a THUMBS UP!!
