Question 301973: One of the delinquency measures was the frequency of alcohol consumption of males and females at “Sunshine High”. Males (mean=2.23;standard deviation=1.59) had a slighter higher average consumption than females (mean=1.95;standard deviation=1.29). Perform a hypothesis test to determine if male and female students differ from one another in the population on alcohol consumption. Kreager surveyed 566 males and 551 females. Use a .05 level of statistical significance. Assume population variances are equal. Treat male students as population 1 and female students as population 2. The obtained t value is____________ . You will "reject" or "fail to reject" the null hypothesis.

One of the delinquency measures was the frequency of alcohol consumption of males and females at “Sunshine High”.
----------------------
Males (mean=2.23;standard deviation=1.59) had a slighter higher average consumption ; n1 = 566
----------------------
Females (mean=1.95;standard deviation=1.29); n2 = 551
----------------------
Perform a hypothesis test to determine if male and female students differ from one another in the population on alcohol consumption.
----------------------
Use a .05 level of statistical significance. Assume population variances are equal. Treat male students as population 1 and female students as population 2. The obtained t value is____________ . You will "reject" or "fail to reject" the null hypothesis.

Ho: u1-u2 = 0
Ha: u1-u2 is not equal to zero
-----------------------
I ran a 2 sample T test and got the following results:
test stat: t = 3.2360
p-value: 0.0012
Conclusion: Since the p-value is less than 5%, reject Ho.
