State whether the chi-square goodness-of-fit test or the chi-square test for independence is appropriate. @ chi-square goodness-of-fit O chi-square test for independence State the degrees of freedom for the test. of Part (b) A student tests whether the professor's speaking style (monotone, dynamic) and student interest (low, high) are independent. State whether the chi-square goodness-of-fit test or the chi-square test for independence is appropriate. O chi-square goodness-of-fit O chi-square test for independence State the degrees of freedom for the test. di= Bpart (9) A health psychologist records the number of below average, average, and overweight individuals in a sample of college students.

In order to determine whether this difference is significant, you collect data on the seating preferences for the students in your class. The data are given below.

O Chi-square Goodness-of-Fit test Chi-square Independence test O Chi-square Dependent variable test O Chi-square Parametric testChi-square test for association. Based on the following output about gender and opinion about legal abortion, where the numbers highlighted in red are the expected counts under the null hypothesis, calculate the value of the chi-square test statistic and the corresponding degree of freedom.
