Answer the questions below

A chi-square test of independence was used to determine whether there was an association between sex and and smoking. Using the output shown below, determine the most appropriate conclusion from among the choices given: Pearson Chi-Square = 2.356, DF = 1, P-Value = 0.125 Select one: 0 a. None of these choices. 0 b. There is an association between sex and smoking. Fewer females and more males than expected were smokers. O c. There may be no association between sex and smoking 0 d. There is an association between sex and smoking. Observed and expected values were the approximately equal. 0 9. There is an association between sex and smoking. More females and fewer males than expected were smokers. A regression analysis is inappropriate when: Select one: 0 a. You have two numerical variables. 0 b. The pattern of points in the scatterplot forms a reasonably straight line. 0 C. You want to make predictions for one variable based on information from another variable. 0 d. There is a pattern in the plot of residuals versus tted values. A chi-square goodness of t test determines whether a set of observed frequencies differs from a set of frequencies. Select one: 0 a. independent. 0 b. constant. 0 0. expected. 0 d. obtained. When using the chi-square test of independence, the larger the value of the chisquare test statistic, the more likely we are to reject the null hypothesis. Select one: 0 True 0 False
