Question

myrna wants to know about how many pairs of jeans middle - school students own. 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 mean, which inference can myrna 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 2.36 is close to 2. It represents the average number of pairs of jeans owned by the surveyed students. So we can infer about the average number of jeans for middle - school students. The first option is too absolute as we can't say all students own jeans from a sample. The third option about preference for cargo pants is not related to the data on the number of jeans. The fourth option is not accurate as the mean is 2.36 not two or less. The second option is a reasonable inference based on the mean value.

Answer:

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