True or False
You test the hypothesis that 20% trimmed mean at time 1 are
equal to the trimmed mean at time 2 using the R function yuend.This
method is the same as testing the hypothesis that trimmed mean of
the difference scores is to zero?

A researcher is interested in testing whether there is a
difference in mean IQ level among people with varying levels of
education (ED). For the ED variable, 1 = no high school degree, 2
= high school graduate, 3 = college graduate. The researcher
produces the following Minitab output. Use the Bonferonni method at
the 3% significance level to test the hypothesis
H0 : μ1 =
μ3 vs H1 :
μ1 ≠ μ3.

Suppose a statistics instructor believes that there is no
difference between the mean test scores of students taking a
morning class and students taking an afternoon class. She takes a
sample from each of her classes, one morning and one afternoon. The
mean and standard deviation for 40 morning students (sample 1) were
78 and 17.8, respectively. The mean and standard deviation for 45
afternoon students (sample 2) were 82.2 and 19.9. Using ?=0.05,
determine if there is a difference...

A college professor wants to estimate the difference in mean
test scores of students who have taken his statistics and genetics
classes in the past 10 years. He selects a random sample of 20
student records from the statistics course and a random sample of
22 student records from the genetics course. These two samples were
independent random samples. The study provided the results shown in
the table below. Construct a 95% confidence interval for the true
difference in population...

A restaurant needs full-time and part-time staffs for daily
operation in the year of 2019. The forecasted number of customers
for Monday is 80. The forecasted number then increases by 10% each
day from Tuesday to Saturday. For example, it is forecasted that
there will be 80*110% customers on Tuesday and 80*(110%)2 customers
on Wednesday, and so on. The forecasted number drops to 70 on
Sunday.
A full-time staff works for the restaurant throughout 2019. She/he

In a random sample of 35 Penn State Shenango students, 17 were
attending full-time. In a random sample of 40 World Campus
students, 13 were attending full-time.
Use Minitab Express to construct a 95% confidence interval to
estimate the difference between the proportions of all Penn State
Shenango and all Penn State World Campus students who are attending
full-time. If assumptions are met, use the normal approximation
method. Remember to copy + paste all relevant Minitab Express
output. Clearly identify...

Part 1.
As a high school biology teacher, you are interested in better
understanding what factors impact your students’ exam grades. To
explore this topic, you asked students to report their interest in
biology as a measure of intrinsic motivation (rated 1-10). To see
if there is any evidence to support your hypothesis that
intrinsically motivated students achieve higher exam scores, you
correlate interest with exam scores. What is the
correlation between biology interest and exam
scores?
