The number of miles USC employees commute to campus is normally distributed. To estimate the mean of this distribution, four employees were sampled. They had a mean commute of 10 miles and a standard deviation of 2 miles. What is the margin of error for the 90 percent confidence interval for the population mean? Round your answer to three decimal places.

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
