Pamplona, Spain is the home of the festival of San Fermin - The Running of the Bulls. The town is in festival mode for a week and a half every year at the beginning of July. There is a running joke in the city, that Pamplona has a baby boom every April - 9 months after San Fermin. To test this claim, a resident takes a random sample of 300 birthdays from native residents and finds the following observed counts:

January	25
February	25
March	27
April	26
May	21
June	26
July	22
August	27
September	21
October	26
November	28
December	26

At the 0.05 level of significance, can it be concluded that births in Pamplona are not equally distributed throughout the 12 months of the year?
