The goodness of fit test is used to examine if there is significant evidence to say thatvthe observed and expected freqencies are from the desired distribution.
Condituis required for performing a goodness of fit test on a data include :
Randomness, sampled Data must have been chosen at random in other to be representative, here, randomness isn't exhibited as Pasquale used more of convenient sampling questioning the first 40 students.
Also, the expected value of the number of sample observation in each level of the variable should be atleast 5.
This is also violated, as the expected values for some of the levels are less than 5
Hence, conditions 1 and 111 are not met
