A study was conducted to investigate for any possible
correlation that may exist between the number of tardiness and the
final grade (%) of the students in statistics class. Based on this
data, Kuya, who is enrolling in the class next trimester, may
anticipate his grade from being tardy every other week (6 times).
What would his estimated grade be?

A study was conducted on the number of hours slept by men and
women. A sample of 18 men slept an average of 6.1 hours a day with
a sample standard deviation of 2.1 hours, whereas a sample of 21
women slept an average of 6.4 hours a day with a sample standard
deviation of 1.7 hours. Use a 0.05 significance level to test the
claim that the average number of hours that there is a difference
between the average...

A study conducted by the MLC on campus found the number of hours
spent at the MLC during a week. The distribution of times spent at
the MLC is normally distributed with an average of 75 minutes and a
standard deviation of 18 minutes.
(a) If a single student that uses the MLC is selected at random,
what is the probability that this student spent between 80 and 100
minutes at the MLC that week?
(b) Now if a sample...

A survey was conducted at a college to determine the number of
hours students spent outside on weekends during the winter. For
students from cold weather climates, the results were M =
8, SD = 1.5. For students from warm-weather climates, the
results were M = 5, SD = 4.2. Explain what these
numbers mean to a person who has never had a course in statistics,
and suggest conclusions the person can draw from these results.
These conclusions use the...

A study was conducted in which students were asked to
estimate the number of calories in a cheeseburger. One group was
asked to do this after thinking about a calorie-laden cheesecake.
A second group was asked to do this after thinking about an organic
fruit salad. The mean number of calories estimated was 771 for the
group that thought about the cheesecake and 1008 for the group that
thought about the organic fruit salad. Suppose that the study was
based...
