1. According to the World Health
Organization's statistics published in 2018,
the lifespan of a person in the
Philippines is 67 years old. A random
sample of 25 obituary notices in the
Philippine Daily Inquirer has an average
mean of 60 years old with a standard
deviation of 19 years. If the life span in the
Philippines is normally distributed, does
this information indicate that the population
mean life span of Filipinos is less than 67
years old? Use 5% level of significance.
2.The manager of a certain TV station
claimed that the average rating of
people watching their noontime teleserye in
Manila is 62.5. A researcher randomly
selected 25 people and asked them their
favorite noontime teleserye. He computed
the mean and obtained 67.8 with standard
deviation of 15.9. Is there a reason to
believe that the manager is correct? Use
0.01 as the level of significance.
3. Massachusetts Institute of Technology
(MIT) determined students Body Mass Index
(BMI) at the opening of classes. It has been
recorded that the average height of female
students is 154.2 centimeters with a
standard deviation of 9 centimeters. The
researcher conducted her own study and
she randomly selected 40 female students.
In his study, He got an average of 156.7
centimeters. Is there a reason to believe the
claims of the school? Use 5% level of
significance in testing the hypothesis.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F717c2933-159a-45cb-ae6b-a3a5a5ade9ab%2F07e1d7e9-31c2-435e-9d89-16ed5ded8321%2F58m77fw_processed.jpeg&w=3840&q=75)
