I am not sure what this question is asking. I would appreciate some guidance.......There are three main assumptions needing to be satisfied before using the independent-samples t-test for testing differences between the genders. Use SPSS to generate the output needed to test the assumptions. Please discuss each one and explain whether each has been met using SPSS output as needed to include histograms, plots, and Levene’s test. Keep in mind if the population value is unknown, it is permissible to infer from sample values. Regardless of sample size, test whether these assumptions are met.

Solution

We have to assume samples and try to do the t test. the assumpotions are

!) parent population is normal.

2) variances are eqaul for the samples

3) samples are independent.

I will take two samples and use SPSS for the analysis.

Since I do not have the population, there is no histogram. If you can provide me with the data, I can do that.

The Levene\'s test is done for equality of varainces. Here since p value is 0.847, the variences are equal. The sample size is small.
