Are births evenly distributed across the days of the week? A sample of 700 birth days was collected with the following results.

Day Sun. Mon. Tues. Wed. Thur. Fri. Sat.

Births 84 110 124 104 94 112 72

Test the hypothesis that the births are equally distributed across the days of the week using an alpha of 0.05.

Which test is used? Is it the Z test?

What is the H0 and the Ha? Is it H0 u = 100 ? Ha u =/ 100 ?

My thinking is that sample of 700 with 7 possible days to give birth, so normal distribution with a mean of 100 births/day......
