Hypothesis test :

The null and alternative hypothesis is

Ho : p1 = p2 = p3 = p4 = 1/4 = 0.25

Ha : At least one proportion not equal.

Chi square goodness of fit test :

Expected frequency = n*p

Month Observed frequency(O) Expected frequency(E) (O-E)^2/E
January 387 1428*0.25 = 357 2.521
February 329 357 2.1961
March 367 357 0.2801
April 345 357 0.4034
Total 1428 1428 5.4006

Test statistic :

= (O-E)^2/E = 5.401

Degree of freedom = df = k-1 = 4-1 = 3

P-value :

P-value corresponding to = 5.401 with df = 3 is 0.1447.

So P-value is 0.1447
