Here aretwo scenarios that can be answered using an appropriate hypothesis test: One is aChi-Squared Test for Independence, and one is a Chi-Squared Goodness of Fit Test (not necessarily in that order):
1. Records of randomly selected births were obtained and categorized according to the day of the week that they occurred (based on data from the National Center for Health Statistics). Because babies are unfamiliar with our schedule of weekdays, a reasonable claim is that births occur on the different days with equal frequency. See the table that follows. Use a 0.01 significance level to test the claim.
Day | Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
# of births | 77 | 110 | 124 | 122 | 120 | 123 | 97 |
2. A random sample of 760 subjects was obtained, and each was tested for left-hand writing. Results are in the table below. Use a 0.05 significance level to test the claim that left-handedness is independent of gender.
Writes with Left Hand? | ||
Yes | No | |
Not Female | 23 | 217 |
Female | 65 | 455 |
