Expert Solution

As per the question, we have to test if the males and females differ in their levels of supporitng others. In others words, we can say that, we have to test there is effect of gender on the supporting levels.

In the hypothesis terms, we have to test

H0: there is no difference in supporting levels of males and females (µmale=µfemale).

H1: there is significant difference in supporting levels of males and females (µmale≠µfemale).

Case-1: with no homogeneity correction - the given ANOVA table is

SUPPORTING_OTHERS
Homogeneity Correction	Cases	Sum of Squares	df	Mean Square	F	p	η²	η² p	ω²
None	GENDER	0.66	1	0.66	0.055	0.815	4.469e -4	4.469e -4	0
	Residuals	1476.332	123	12.003

In this case, we have the p-value = 0.815, which is obviously greater than 0.05 and it suggests that we do not have enough evidence against H0 to reject it, so we fail to reject H0 at 0.05 level of significance and we can conclude that there is no difference in supporting levels of males and females.

Case-2: welch homogeneity correction - the given ANOVA table is

SUPPORTING_OTHERS
Homogeneity Correction	Cases	Sum of Squares	df	Mean Square	F	p	η²	η² p	ω²
Welch	GENDER	0.66	1	0.66	0.053	0.819	4.469e -4	4.469e -4	0
	Residuals	1476.332	85.355	17.296

In this case, we have the p-value = 0.819, which is obviously greater than 0.05 and it suggests that we do not have enough evidence against H0 to reject it, so we fail to reject H0 at 0.05 level of significance and we can conclude that there is no difference in supporting levels of males and females.

Finally in both the cases, we fail to reject the null hypothesis and we can conclude that males and females do not differ in their levels of supporting others.

Numerous studies have found that males report higher self-esteem than females, especially for adolescents. Typical results show a mean self-esteem score of M=39.0 with SS=60.2 for a sample of n=10 males and a mean self-esteem score of M=35.4 with SS=69.4 for a sample of n=12 females. 1. Do the results indicate that self-esteem is significantly higher for males ? Use a two-tailed test with a=.01. Use all 4 steps 2. Calculate the estimated d (cohen's d) and classify the effect...

1. In many animal species the males and females differ slightly in structure, coloring, and/or size. The hominid species Australopithecus is thought to have lived about 3.2 million years ago. (“Lucy,” the famous near complete skeleton discovered in 1974, is an Australopithecus .) Forensic anthropologists use partial skeletal remains to estimate the mass of an individual. The data below are estimates of masses from partial skeletal remains of this species found in sub-Saharan Africa. Appropriate graphical displays of the data...
