The following describes the unemployment rate in the United States from 2003 to 2013. In 2003, the
unemployment rate was at 6.3%. The unemployment
rate began to fall over the years and reached a
minimum of about 4.4% in 2007. A recession that
began in 2007 caused the unemployment rate to
increase over a two-year period and reach a
maximum of about 10% in 2009. The unemployment
rate then decreased over the next four years to about
7.0% in 2013. Sketch a graph of the function.

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.
