1. WHat is the null Hypothesis
2. WHat is the computed value of the test statistic t?
3. What is the p value for this test statistic
4. What decision is made about the null hypothesis using a alpha = 0.05
You can put this solution on YOUR website! Assume that the population standard deviations are equal for income mutual funds and growth mutual funds. Use the following sample data to test whether there is a difference in the mean yields of the two funds at the 0.05 level of significance.

1. WHat is the null Hypothesis
Ho: u1-u2 = 0
Ha: u1-u2 # 0
=====================
2. WHat is the computed value of the test statistic t?
t = 2.7017
3. What is the p value for this test statistic
p = 0.0086
4. What decision is made about the null hypothesis using a alpha = 0.05
Since the p-value is less than 5%, reject Ho at the 5% level of significance.
