???????

find the rejection region necessary for testing at the \( 0.05 \) level of significance whether there is a relationship between defect rate and years of experience Reject \( H_{0} \) if the test statistic \( >16.919 \) Reject \( H_{0} \) if the test statistic \( >15.507 \) Reject \( H_{0} \) if the test statistic \( >11.143 \) Reject \( H_{0} \) if the test statistic \( >9.488 \) QUESTION 13 of the cell for 1 to 4 years of training time and a high defect rate, what is the contribution to the overall chi square statistic for the independence test? \( 0.015 \) \( 0.1296 \) \( 0.0144 \) \( 0.36 \) what is the expected number of employees with less than 1 year of training time and a high defect rate? \( 4.17 \) \( 4.6 \) \( 5.28 \) \( 9.17 \) QUESTION 15 what is the expected number of employees with 1 to 4 years of training time and a high defect rate? \( 6.67 \) \( 8.64 \) 12 6
