The null and alternative hypotheses for a population proportion, as well as the sample results, are given. UseStatKey or other technology to generate a randomization distribution and calculate a p-value. StatKey tip: Use"Test for a Single Proportion" and then "Edit Data" to enter the sample information.Hypotheses: Ho: p = 0.5 vs Ha:p # 0.5;280.70 with n = 4040p-value = iSample data: pRound the p-value to three decimal places.==

A union of restaurant and foodservice workers would like to estimate the mean hourly wage, u, of foodservice workers in the U.S. this year The mean hourly wage last year was $8.08, and there is good reason to believe that this year's value is different from last year's. The union decides to do a statistical test to see if the value has indeed changed. The union chooses a random sample of this year's wages, computes the mean of the sample to be $7.78, and computes the standard deviation of the sample to be $1.20. Based on this information, complete the parts below. (a) What are the null hypothesis H. and the alternative hypothesis H₁ that should be used for the test? H₂ : O H₁ :0 (b) Suppose that the union decides not to reject the null hypothesis. What sort of error might it be making?
