Suppose a random sample of 320 students was asked to indicate which of 4 candy 'items' they preferred. The results were: 12. York Mints Peanut Butter Cups Snickers Kit Kat 90 90 70 70 What is the calculated value of Chi-square [see the One-way Chi-square Example file and/or the Handout file (pp. 303-305)]? 13. In Question 12, how many degrees of freedom do you have? In Question 12, at the .05 level of significance, what would the critical value of Chi-square be? BE SURE TO ROUND OFF TO 2 DECIMAL PLACES. 14. 15. In Question 12, at the .05 level of significance, you should reject the null hypothesis (T/F)? 16. In Question 12, at the .05 level of significance, the results are statistically significant (T/F)?
