1. For her project, Maria bought 50 small bags of jelly beans. The average number of jelly beans in a small bag is 27. It is known that the standard deviation is 3 jelly beans. Maria conducts a hypothesis test to determine if the average number of jelly beans in a small bag is more than 25. The level of significance is 1%. H o : µ ≤ 25H a : µ > 25

2. = the average number of jelly beans in a small bag of jelly beans. Distribution for the Test: Normal for Averages

3. Test statistic: z = 4.71 Standardized score, z-score, for p-value: USE A ZTEST.

4. Decision: REJECT H 0. Conclusion: There is sufficient evidence to conclude that the average number of jelly beans in a small bag is more than 25.
