The mean age of the 30 members of the Ft. Wayne Comets is 28.
After the
current season, five members whose mean age is 35 will retire. They
will be
replaced by five new members whose mean age is 24. What will the
new
mean age of the Comets be ?
Homework Answers
Solution :
Given that,
The mean age of the 30 members of the Ft. Wayne Comets is 28
so, 30 * 28 = 840
After the current season, five members whose mean age is 35 will retire then
5 * 35 = 175
840 - 175 = 665
They will be replaced by five new members whose mean age is 24,
5 * 24 = 120
So, the new mean age of the Comets be ,
New age = (665 + 120) / 30 = 785 / 30 = 26.167

An experiment is conducted involving 20 children divided into 10 pairs. The members of each pair are carefully matched so that they are similar with respect to sex, age, and IQ and previous mathematic training. They had not yet studied multiplication. One member of each pair is randomly chosen and taught multiplication using method A. The other member of the pair is taught multiplication using method B. Test scores for the 20 children after the learning experience are as follow:...

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...
