Two sample t-test:
Suppose you are interested in deciding if the 1990 toyota four runner has been equally as reliable as the 1990 honda passport. You go out and randomly sample 5 people who own a 1990 toyota and 5 other people who own a 1990 honda and ask them how often they take their vehicles in for maintenance. Here is the data (in thousands of miles)
Honda: 29, 33, 28, 31, 27
Toyota: 31, 35, 32, 34, 30
a. state the null and the alternative hypotheses
b. compute the means and standard deviations of the two samples
c. compute the two-sample t-statistic
d. how many degrees of freedom?
e. compute p-value
f. at an alpha= 0.05 would you accept of reject the null hypothesis?

Paired Samples t-test (30pts)Suppose you are
interested in deciding if a particular diet is effective in
changing people’s weight. You decide to run a “within subject”
experiment. You select 6 people and weight each of them. Two weeks,
you weight them again. For each person, you compute how much weight
they lost over this period. This is what you find:Non-diet(subject
1-6): 0,8,3,2,-10,-1.You then put them on the diet and weigh them
again after two weeks and compute how much they...

Suppose you are interested in buying a new Toyota Corolla. You
are standing on the sales lot looking at a model with different
options. The list price is on the vehicle. As a salesperson
approaches, you wonder what the dealer invoice price is for this
model with its options. The following data are based on a random
selection of Toyota Corollas of different models and options. Let
y be the dealer invoice (in thousands of dollars) for the
given vehicle....
