See attached file for better formatting.

For the following problem statement, identify the hypothesis H0 and the alternative hypotheses H1.

Suppose that a company claims that their weekly losses are no more than \$2,500. A sample of 40 random weeks finds a mean weekly loss of \$3,200 with an estimated population standard deviation of \$750. Test their claim at the a=0.05 level.

H0: (&#956;, &#963;,or p),( &#8800;,&#8804;,&#8805;,<, or =), (\$3,200, \$2,500, 40, 0.05, 750)
H1: (&#956;, &#963;,or p),( &#8800;,&#8804;,&#8805;,<, or =), (\$3,200, \$2,500, 40, 0.05, 750)
