Welcome! The new FreeMathHelp.com forum is live. We've moved from VB4 to Xenforo 2.1 as our underlying software. Hopefully you find the upgrade to be a positive change. Please feel free to reach out as issues arise -- things will be a little different, and minor issues will no doubt crop up.

You are given the following data. Test the claim that there is a difference in the means of the two groups. Use = 0.05.
Group A Group B
= 10 = 2
= 1.0 = 0.1
= 99 = 52
• State the null and alternate hypotheses
• Determine which test statistic applies, and calculate it
• Determine the critical value(s).
• State your decision: Should the null hypothesis be rejected?
