Determine the null and alternative hypotheses.
H0:
▼
Police calls occur with the same frequency on the different days of the week.
At least two days have a different frequency of calls than the other days.
At least one day has a different frequency of calls than the other days.
Police calls occur with all different frequencies on the different days of the week.
H1:
▼
At least one day has a different frequency of calls than the other days.
Police calls occur with all different frequencies on the different days of the week.
At least two days have a different frequency of calls than the other days.
Police calls occur with the same frequency on the different days of the week.

H0.
There is
insufficient
evidence to warrant rejection of the claim that the different days of the week have the same frequencies of police calls.What is the fundamental error with this analysis?
Because October has 31 days, each day of the week occurs the same number of times as the other days of the week.
Because October has 31 days, three of the days of the week occur more often than the other days of the week.
Because October has 31 days, one of the days of the week occur more often than the other days of the week.
Because October has 31 days, two of the days of the week occur more often than the other days of the week.
