Following are observed frequencies The null hypothesis is Ho

Following are observed frequencies. The null hypothesis is Ho p 0.45, p -0.25, p3 0.2, p4 0.05. 0.05 Category 1 2 3 4 5 Observed 59 32 12 22 23 Compute the value of Select one: A. 73.700 B. 76.082 O C. 11.070 D. 9.488

Solution

Doing an observed/expected value table,          
O   E   (O - E)^2/E  
59   66.6   0.867267267  
32   37   0.675675676  
12   29.6   10.46486486  
22   7.4   28.80540541  
23   7.4   32.88648649  
Using chi^2 = Sum[(O - E)^2/E],          
          
chi^2 =    73.6996997 = 73.700 [ANSWER, OPTION A]
