1. The average length of night (sunset to sunrise) in Manila is said to be 12.2 hours. A group of students said that in February, it will be shorter. They do a study about this and choose 14 randomly selected days in February. The computed sample average is 11.19 hours with a standard deviation of 0.25 hours. Is there enough evidence for the students' claim? Use a=0.05.
