Question

myma wants to know about how many pairs of jeans middle school students own. she did not have time to ask all 257 middle school students, so she surveyed a random sample of 25 students. the results below display the number of pairs of jeans each surveyed student owns. 3, 4, 2, 1, 3, 1, 2, 4, 2, 3, 1, 2, 4, 2, 3, 2, 2, 6, 1, 1, 2, 4, 1, 1, 2 the mean of her data is 2.36 pairs of jeans. from the given data and the calculated mean, which inference could myma make? all middle school students own jeans. the average middle school student owns around two pairs of jeans. most seventh - grade students prefer cargo pants to jeans. an average middle school student owns three or more jeans.

Explanation:

The mean of the sample data is 2.36 pairs of jeans. This value is close to 2. An inference is made based on sample - mean to estimate the population (all middle - school students). Since the mean is around 2, it can be inferred that the average middle - school student owns around two pairs of jeans. The data doesn't support claims about all students owning jeans, preferences of seventh - grade students, or the average student owning three or more jeans.

Answer:

The average middle school student owns around two pairs of jeans.
