39) All of the following are assumptions of the one-sample t-test EXCEPT: a scores come from independent observations b. the population that is sampled is skewed c. the population that is sampled is normal d none of the above Chapter 10: The t-test for two independent samples t measures i-test EXCEPT a observations within each sample are independent b. the two populations that were sampled from are normal c the two populations that were sampled from have equal variances (homogeneity) d the two populations that were sampled from have unequal variances (heterogeneity) 41.) With respect to t-tests, within-subjects designs utilizing the f-statistic: participant is measured more than once a include one sample, in which each b. include one sample, in which each participant is measured only once c. ucluds two samples, in which each participant is measured more than once d. include two samples, in which each participant is measured only once 42.) With respect to t-tests, between-subjects designs utilizing the f-statistic a inclade one sample, in which each participant is measured more than once b. include one sample, in which each participant is measured only once c include two samples, in which each participant is measured more than once d. includc two samples, in which each participant is measured only once 43.) All of the following apply to the concept of pooled variance EXCEPT a it is used in between-subjects t-tests b. it is obtained by averaging two separate sample variances c. it allows the bigger sample to carry more weight in determining the final value for variance d. it is used in within-subjects -Hests Chapter 11: The -test for two related samples 44) A primary disadvantage of repeated-measures i-tests is: a there is no way to control for individual differences b. the order in which treatments are presented may influence the treatment effect c less subjects are needed for equivalent degrees of statistical power d these designs are not useful 8 of 3825 words

39) B option

The assumptions of the one-sample t-test are: 1. The data are continuous (not discrete). 2. The data follow the normal probability distribution. 3. The sample is a simple random sample from its population. Each individual in the population has an equal probability of being selected in the sample.
