She finds that Erica filled 56 orders, Jen filled 18 , Heather filled 14 , and Tonya filled 12 What is the value of the chi-square test statistic and the cap p -value of this test? Use the chi-square distribution table.
Answer
A
chi squared is equal to 11 point 2 0 , cap p -value is between 0 point 0 1 and 0 point 0 2
B
chi squared is equal to 8 point 5 3 , cap p -value is between 0 point 0 2 5 and 0 point 0 5
C
chi squared is equal to 8 point 5 3 , cap p -value is between 0 point 0 5 and 0 point 1 0
D
chi squared is equal to 11 point 2 0 , cap p -value is between 0 point 0 2 5 and 0 point 0 5
