In a department store, the ratio of the number of sales of a certain item in three different weekends is expected to follow a normal distribution. It is hypothesized that the number of sold items in the three weekends should follow the expected ratio. To investigate such a claim, a sample of fifty of these sold items was tracked back to the weekend where the sales occurred. The item sales results are provided in the table below. Test the hypothesis indicated using alpha = 1%

(a)  Statisticobs > Statisticcri = 7.824; Reject H0

(b)  Statisticobs < Statisticcri = 7.824; Do Not Reject H0

(c)  Statisticobs > Statisticcri = 9.210; Reject H0

(d)  Statisticobs < Statisticcri = 9.837; Do Not Reject H0

(e)  none of the above
