The table below lists the number of crimes reported at a police station on each day of the week for the past three months.
Day of the WeekNumber of Crimes Monday Tuesday Wednesday Thursday Friday Saturday Sunday
The null hypothesis for the goodness-of-fit test is that the number of crimes reported at this police station is the same for each day of the week. What is the expected number of crimes reported on a Thursday?
Homework Answers
Total no. of Crimes in a week from Monday to Sunday is equal to 21+10+13+16+25+29+26 = 140
Here, the Null hypothesis for the goodness of fit can be defined as,
H0: Expected number of crimes reported at a police station on each day = 140/7=20.
Expected number of crimes reported on Thursday = 20 (same for each day in a week)
