Suppose you are statistically comparing the means of two populations with the following hypotheses: ?0: ?1 ≤ ?2, ?1: ?1 > ?2. The sample sizes from the two populations are ?1 = 16 and ?2 = 13, and the variances of the two populations are assumed to be unknown but equal. Find the bounds for the ?-values if using the book, or the explicit ?-values if using Excel, for the following test statistics associated with this problem. Draw conclusions with 95% confidence. a. 1.81 (USING THE APPROPRIATE TABLE IN THE TEXTBOOK) b. 1.12 (USING THE APPROPRIATE TABLE IN THE TEXTBOOK) c. 1.95 (USING THE APPROPRIATE EXCEL FUNCTION) d. 3.68 (USING THE APPROPRIATE EXCEL FUNCTION)

- Define two distinct populations and two independent samples,
for example: Population 1: Male Students at DVC, Population 2:
Female Students at DVC. Two populations or samples are independent
if the values selected from one population are not related to or
somehow naturally paired or matched with the values selected from
the other population.

Using the methods in Section 11.1, test the hypothesis (α =
0.05) that the population proportions of red and brown are equal
(pred = pbrown). You are testing if their proportions are equal to
one another. NOTE: These are NOT independent samples, but we will
use this approach anyway to practice the method. This also means
that n1 and n2 will both be the total number of candies in all the
bags. The “x” values for red and brown are...
