The participants were asked to opt for one meal among which 60 + x chose pizza, 60 chose burrito, and 60 -x chose falafel. According to Ho the expected number of choices for each meal is 60. The table which describes this goodness of fit test is given below. The degree of freedom of this table is DF = 2 which means that we can reject Ho with the significance level = 0.05 when x 5.99.
