Algebra.Com's Answer #307139 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! A union of restaurant and foodservice workers would like to estimate this year's mean hourly wage, , of foodservice workers in the U.S. Last year's mean hourly wage was (??), and there is reason to believe that this year's value is less than last year's. \n" ); document.write( "-------------------------------- \n" ); document.write( "The union decides to do a statistical test to see if the value has indeed decreased. The union chooses a random sample of this year's wages, computes the mean of the sample to be (??), and computes the standard deviation of the sample to be (??) . \n" ); document.write( "Questions: \n" ); document.write( "1. what are the null hypothesis and the alternative hypothesis that should be used for the test? \n" ); document.write( "2. In the context of this test, what is a TYPE II error? \n" ); document.write( "3. Suppose that the union decides to reject the null hypothesis. What sort of error might it be making? \n" ); document.write( "---- \n" ); document.write( "Please check the text of your posted problem. Three necessary numbers \n" ); document.write( "are missing. \n" ); document.write( "---- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============ \n" ); document.write( " \n" ); document.write( " |
