Question

Screenshot (14) is the starting and Screenshot (15) is the second half. 

In a two-way Chi-square, suppose there are 2 rows and 5 columns. In this situation, how many degrees of freedom would you have? ANSWER WITH A NUMBER 18. 19. Diagrammed below are the results of a study that asked 300 men and 300 women if they were 'for' or 'against' Delta College being a smoke-free campus. For Against Men 170 130 Women 230 70 What is the calculated value of Chi-square [see the Handout file (pp. 309-311)]? BE SURE TO ROUND OFF ALL DECIMALS TO 2 DECIMAL PLACES. 20. In Question 19, how many degrees of freedom would you have? ANSWER WITH A NUMBER 21. In Question 19, at the .05 level of significance, what would the critical value of Chi-square be? BE SURE TO ROUND OFF TO 2 DECIMAL PLACES. 22. In Question 19, at the .05 level of significance, you should reject the null hypothesis (T/F)? In Question 19, at the .05 level of significance, there is a significant relationship between gender and opinion on Delta College being a smoke-free campus (T/F)? 23.

Cramer's phi indicates the strength of the relationship in a two-way Chi-square situation (T/F)? In Question 19, what is the numerical value of Cramer's phi (do not take the square root until the last step)? Would the value of Cramer's phi in Question 25 be considered weak, moderate, or strong?
