To test effectiveness of treatment, a sample of n = 25 people is chosen from normal population with mean of µ = 60. After treatment is administered to individuals in sample, sample mean is found to be M = 55.
a. Determine Cohen's d measure effect size for both tests (σ = 20 and σ = 10).b. Explain how sample size influence outcome of the hypothesis test. How does sample size influence measures of effect size?
Which of the following is true about the expected value of perfect information. It is the amount you would pay for any sample study.
At 0.05 level of significance, is there evidence of significant relationship between age group and where people mainly get their news? If so, describe the relationship.
Give a probability distribution for the following: In 1992, the Big 10 collegiate sports conference moved to have women compose at least 40% of its athletes within 5 years.
If a researcher decides to use multiple comparisons in a study with three conditions, what is the probability of a Type I error across these comparisons? Use the Bonferroni adjustment to determine the suggested alpha level.
Give an example of a situation in which multiple linear regression, discriminate analysis, canonical correlation, and multivariate analysis of variance might be used.
We recalculated our comparison of ideal number of children, this time only for women, separating them into two groups, those who indicated that they were "very happy" or "not at all happy" with life.
Compute the range, variance, standard deviation, and coefficient of variation. Compute the Z scores. Are there any outliers?
Construct a 95 percent confidence interval for the true mean.
Suppose there are two samples of size 6 and 7, with a rank sum of 58 in the sample of size 6. Using the Wilcoxon rank-sum test, evaluate the significance of the results, assuming there are no ties.
In a regression analysis involving 27 observations, the following estimated regression equation was developed.
Suppose the random variable X is normally distributed with mean =50 and standard deviation =7 calculate P(X).
A normal population has a mean of 75 and a standard deviation of 5. You select a sample of 40. Compute the probability the sample mean is:
