Question
  1. Consider an experiment involving n = 300 trials and K=5 cells. The observed frequencies resulting from the experiment are show below, and the null hypothesis to be tested is as follows:  H0 : p1 = .1; p2 = .2, p3 = .3, p4 = .2, p5 = .2

Test the hypothesis at the 1% significance level

Cell                       1          2          3          4          5

Frequency             24        64        84        72        56

Expert Solution
Step 1

 

Null hypothesis; H0: p1 =p1=0.1, p2=0.2, p3=0.3, p4=0.2, p4=0.2

 

 

Under the null hypothesis, the expected frequency and the test statistic is calculated in the following table:
