a. Find the degrees of freedom for unequal variance test. (Round down your answer to the nearest whole number.)b. State the decision rule for 0.01 significance level. (Round your answer to 3 decimal places.)c. Compute the value of the test statistic. (Round your answer to 3 decimal places.)d. What is your decision regarding the null hypothesis? Use the 0.01 significance level.

The null and alternate hypotheses are: Ho: HIS H2 HI: M1 > H2 A random sample of 26 items from the first population showed a mean of 109 and a standard deviation of 11. A sample of 18 items for the second population showed a mean of 104 and a standard deviation of 7. Assume the sample populations do not have equal standard deviations and use the 0.01 significant level. Required: a. Find the degrees of freedom for unequal variance test. (Round down your answer to the nearest whole number.) Degrees of freedom ces b. State the decision rule for 0.01 significance level. (Round your answer to 3 decimal places.) Reject Ho if t> c. Compute the value of the test statistic. (Round your answer to 3 decimal places.)
