As per the HOMEWORKLIB POLICY, we are advised to do one question at a time so i am attempting 30th.
30. This would be a paired sample t - test since the samples are dependent. Morever, this would be a two tailed test.
Degrees of freedom = n - 1 = 5 - 1 = 4
For 4 degrees of freedom and 0.05 level of significance, two tailed critical value will be:
t0 = 2.776

Do the Academy Awards involve discrimination based on age? Listed below are the ages of actresses and actors at the times that they won Oscars in the Best Actress and Best Actor categories. the ages are listed in order, beginning with the first Academy Awards ceremony in 1928. (Note: in 1968 there was a tie in the Best Actress category, and the mean of the two ages is used; in 1932 there was a tie in the Best Actor category,...

Let's now perform a mean-matched pairs test to test the claim that there is no mean difference between the age of males and females. For the context of this problem, d=x2−x1where the first data set represents actress (female) ages and the second data set represents male (actor) ages. We'll continue to use a significance of 0.05. You believe the population of difference scores is normally distributed, but you do not know the standard deviation. H0: μd=0 H1:μd≠0 Actress Age Actor...

Solve all parts and show working:
(i) :
Use a 5% significance level to test the claim that the
unsuccessful applicants are from a population with a greater mean
age than the mean age of successful applicants. Based on the
result, does there appear to be discrimination based on age? What
did you use to get the answer?
(ii): Is it a parametric or non-parametric test? If it

Given two dependent random samples with the following results: Population 1: 44, 39, 42, 31, 40, 36, 42 Population 2: 32, 32,, 27, 18, 38, 30, 37 Use this data to find the 95% confidence interval for the true difference between the population means. Let d=(Population 1 entry)−(Population 2 entry) Assume that both populations are normally distributed. Find the mean of the paired differences, find the critical value that should be used in constructing the confidence interval, and find the...
