Compare mean cholesterol levels of a sample of 100 vegetarians with a sample of 100 nonvegetarians. I would use logistic regression t-test for independent means chi-square test factorial ANOVA multiple regression one-sample Z test one-way ANOVA MANOVA linear regression t-test for dependent means (paired t-test) I want to predict breast cancer (0 = no cancer, 1 = cancer) based on body mass index (BMI). I would use one-sample Z test one-way ANOVA MANOVA logistic regression factorial ANOVA t-test for dependent means (paired t-test) multiple regression linear regression chi-square test t-test for independent means

Explanation / Answer

1) To compare mean cholesterol levels of 100 vegetarians with a sample of 100 non vegetarians.

For comparing mean of two independent sample we use t-test for independent means.

Because population standard deviations are unknow.

2) 0 = no cancer ; 1 = cancer

We have to predict BMI

In this case we use logistic regression.

Because in logistic regression has responses are sucess and failure.

In this case sucess is cancer and failure is no cancer.

So we use for predicting BMI we use logistic regression.
