We have created a scientific experiment where one class of 40 people were taught using a flipped classroom. This class had an average score of 85. Also, we have observed from similar classes that σ = 3. We would like to test whether or not a flipped classroom improves the average grade compared to the standard class room’s mean grade of 84 with a standard deviation of 4. No students were in both the standard and flipped classrooms.
9. What is the population and sample for this problem?
10. What is the null and alternate hypothesis here?
11. Perform an α = 0.05 hypothesis test you have specified above. (Hint: 0.05 is the cutoff) [Indicate what the p-value is and whether or not you reject or fail to reject the null]
12. Perform an α = 0.01 hypothesis test you have specified above. (Hint: 0.01 is the cutoff)[Indicate what the p-value is and whether or not you reject or fail to reject the null]

in an experiment on learning 70 rats were taught to
navigate a maze during a 3 week training period. half the rats
(n=35) were randomly selected to receive cocaine injections for a
week while the other half received sodium placebos.
after the drug treatment the rats were then tested in
the maze and their response times were recorded. for rats who
received cocaine the sample mean was 16.83 seconds and ss=
903.04
for the rats who received the placebo the...

The current Pandemic has created situations where people have
lost their job, been forced to be isolated from others or are
having more expectations place on them with fewer resources. Given
the current social unrest being reflected in many cities around the
country, police officers, business managers, politicians are
retiring or resigning from their position. That leaves their
employer with a personnel gap that has to be filled. What
can organizational leaders do to reduce workplace stress related to
civil...

Two sections of a class in statistics were taught by two
different methods. Students’ scores on a standardized test are
shown in Table 5.12 . Do the results present evidence of a
difference in the effectiveness of the two methods? (Use α
= 0.05.)
Class A: 74, 97, 79, 88, 78, 93, 76, 75, 82, 86, 100, 94
Class B: 78, 92, 94, 78, 71, 85, 70, 79, 76, 93, 82, 69, 84

An experiment is performed to compare the average reading scores
of second grade children taught using four different methods.
Students are randomly assigned to the four groups with 20 students
per group. An analysis of variance is to be used to analyze the
data. The following is a partially completed ANOVA table. Fill in
the remaining details (2 pts per blank – 12 possible points):
SS total = ?

In an experiment reported in the scientific literature, male
cockroaches were made to run at different speeds on a miniature
treadmill while their oxygen consumption was measured. In one hour
the average cockroach running at 0.08km/hr consumed 0.8 mL of O2 at
1 atm pressure and 24 ?C per gram of insect weight.
a)
How many moles of O2 would be consumed in 1 hr by a 5.4?g
cockroach moving at this speed?
b)
This same cockroach is caught by...
