Two fuel additives are being tested to determine their effect on gasoline mileage. Seven cars were tested with additive 1 and nine cars were tested with additive 2. The following data show the miles per gallon obtained with the two additives.
| Additive 1 | Additive 2 |
|---|---|
| 18.3 | 18.7 |
| 19.4 | 18.8 |
| 20.1 | 21.3 |
| 15.7 | 20.0 |
| 18.2 | 23.1 |
| 18.6 | 18.7 |
| 17.5 | 19.8 |
| 20.7 | |
| 19.2 |
Find the value of the test statistic and p-value.
please do step by step? I saw there was a similar problem but table 8 in Appendix B Tables isn't there so I wasn't able to finish the answer.

Two fuel additives are being tested to determine their effect on
gasoline mileage. Seven cars were tested with additive 1 and nine
cars were tested with additive 2. Data: Additive 1 - 17.3,18.4,
19.1, 17.7, 17.2, 17.6, 18.5; Additive 2 - 18.7, 18.8, 20.3, 20.0,
21.1, 18.7, 18.8, 20.7, 21.2. The following data show the miles per
gallon obtained with the two additives. I am struggling to
determine the p-value.

Twenty-five different cars were tested, and their weights (in
pounds) and mileage (miles per gallon) were measured. The
regression of mileage on weight has the MINITAB regression output

In automobile mileage and gasoline-consumption testing, 6
automobiles were road tested for 300 miles in both city and highway
driving conditions. The following data were recorded for
miles-per-gallon performance. City 16.2 16.7 15.9 14.4 16 16.2
Highway 19.4 20.6 18.3 18.6 18.6 18.7 Use mean, median, and mode to
make a statement about the difference in performance for city and
highway driving. Which area of Statistics helps you to either
validate or disprove such a statement and why?

1. Three different makes of cars were tested for fuel
efficiency. For each make of car eighteen automobiles were randomly
selected and subjected to standard driving procedures. Using the
data from the following results compute the between treatments
estimate of σ² and the within treatments estimate of σ². At the
α=.05 level of significance, can the null hypothesis, that all fuel
economies are the same, be rejected? Construct the ANOVA table for
this data. (Use the formulas to compute the...

Two different formulations of an oxygenated motor fuel are being
tested to study their road octane numbers. The population variance
of road octane number for formulation 1 is =1.5, and for
formulation 2, it is =1.2. Two random samples of size =15 and =20
are tested, and the mean road octane numbers observed are =89.6 and
=92.5. Assume normality.
a.) Construct a 95% two-sided confidence interval on the
difference in mean road octane number.
b.) If formulation 2 produces a...

The ACME Fuel Company is testing three gasoline additives that
potentially improve miles per gallon (mpg). Data on the mpg
increases are listed below.
(a) For each of the three additives, make boxplots, probability
plots, run Anderson-Darling tests, and Shapiro-Wilks tests to check
for normality.
(b) Based the results in part (a), which test (Hartley’s F-max,
Bartlett’s, Levene’s) is best to use to check for a difference
between the variances of mpg increases for the three additives?
(c) Run the...

Two types of medication for hives are being tested to determine
if there is a difference in the proportions of adult
patient reactions. Twenty out of a random sample
of 200 adults given medication A still had hives 30
minutes after taking the medication. Twelve out of
another random sample of 180 adults given
medication B still had hives 30 minutes after taking the
medication. Test at a 1% level of significance.
1) For this hypothesis test, the null and...
