Question 322827: This problem tells me to use the variances unequal formula...could you provide it...thank you.
Mauricio Cruz, a wine merchant for Cruz's Spirits Emporium, wants to determine if the average price of imported wine is less than the average price of domestic wine. The data obtained is shown in the table below.
Imported Wine Domestic Wine
X 7.03 9.78
s 2.31 3.62
n 15 16
40. What is the test value? Use a = 0.05. (Use the variances unequal formula)
A) –4.53 B) –2.54 C) –2.50 D) –6.97
You can put this solution on YOUR website! t = [(x1bar-x2bar)-(u1 - u2)]/[sqrt[s1^2/n1 + s2^2/n2]
df = smaller of n1-1 and n2-1
===================================
Note: I ran a 2-SampleT test on my TI-84 calculator
and got a test statistic of t = -2.5372
==========================================
