A report by the New York Times in 2022 indicated that, on average, a married woman in the United States goes out with her female friends an average of 5.7 times peryear. A student at Century College conducts a study of her own by randomly surveying married women in White Bear Lake and obtained this data for the number of times in a year:
3 1 1 3 7 2 9 4
6 4 3 8 0 5 6 4
0 1 3 0
