Question: A wedding caterer randomly selects clients from the past few years & records the months in which the wedding receptions were held. The results are listed below [based on data from The Amazing Almanac].

Month	Observed Frequency (O)	Expected Frequency (E)
January	5	9.167
February	8	9.167
March	6	9.167
April	8	9.167
May	11	9.167
June	14	9.167
July	10	9.167
August	9	9.167
September	10	9.167
October	12	9.167
November	8	9.167
December	9	9.167
TOTAL	110	110

[A] Is there sufficient evidence to reject the null hypothesis?

[B] According to your conclusion in step d, do the data provide significant evidence to conclude that weddings are held in different months with the same frequency?
