4.A researcher collected Pet Shop data in order to examine whether pet stores displayed different types of reptiles during different times of the year. The researcher visited 12 stores four times during the next year. The times were chosen close to the following holidays: Valentine's Day, July 4th, Halloween, and Christmas. During each visit, the researcher recorded if the shop displayed only snakes or lizards (coded 1) or both types of reptiles (snakes and lizards coded 2). Test the null hypothesis that stores are equally likely to display both kinds of reptiles at all times of the year at alpha equal to 0.05. Namely, there is an equally likely chance that both kinds of reptiles will be displayed near Valentine's Day as near July 4th as near Halloween as near Christmas, and therefore, time of year does not matter.
