Answer #1

Chi square test statistics is appropriate to identify the association between two dichotomous variables

Relationship between two categorical variables or difference in two or more population proportions The observed counts in a two-way table Categorical

Is there a relationship between smoking and lung cancer?

Do the proportions of students in each class who smoke differ?

Ho: The two variables are not related

Ha: The two variables are related

The researcher interest in odds of out come occurring are find by using chi square test statistic

11 . Choosing the appropriate test statistic You are interested in the difference between two population means. Both populations are normally distributed, and the population variances σ212 and σ222 are known. You use an independent samples experiment to provide the data for your study. What is the appropriate test statistic? F = √[2/n1 + 2/n2] F = s1/s2 z = (x̄1 – x̄2) / √[σ2/n1 + σ2/n2] z = (p̂1 – p̂2) / √[p̂(1 – p̂)(1/n1 + 1/n2)] Suppose instead...

A regression analysis is a statistical assessment of the association between two variables, one of which is dependent and the other, independent. The dependent variable is y and the independent variable is x. Regression analysis is used to find the relationships between these variables. Variables within a regression analysis can be negatively correlated or positively correlated. A situation in which one could model a regression analysis could be the association of hours studied and a grade on a test. The...
