The Empirical Rule
Example: Suppose the national average for the math portion of SAT test is 515
and the standard deviation is approximately 100. Assume that the distribution
for SAT is bell-shaped.
What percentage of students have an SAT m
Suppose that we have a sample space with five equally
likely experimental outcomes: E1, E2, E3, E4, E5. Let
A = cfw_E1, E2
B = cfw_E3, E4
C = cfw_E2, E3, E5
From five equally likely experimental outcomes,
P(E1 ) = P(E2) = P(E3 ) = P(E4) = P(E5 ) =
Consider the following hypothesis test:
Ha: > 12
A sample of 25 provided a sample mean of 14 and a
sample standard deviation s = 4.32.
Compute the value of the test statistic.
t-stat = 2.31
What is a range for the p-value?

Chapter8: Interval Estimation
Recall that statistical inference is the use of
sample data to make judgments about a
population of interest.
Our sample must be representative
Generally, we use inference in two ways
Note: For stem-and-leaf diagram, the leaf unit can be 0.1, 1, 10, 100 and so on.
