The null and alternative hypotheses for a population proportion, as well as the sample results, are given. Use StatKey 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: H0:p=0.5 vs Ha:p<⁢0.5; Sample data: p^=38/100=0.38 with n=100 Round the p-value to three decimal places. p-value = Enter your answer in accordance to the question statement

Consider conducting a hypothesis test in which the null and alternative hypotheses are: Ho: ? ? c Ha: ? > c Where c is some hypothesized value. Suppose the significance level is 0.02, the test statistic is positive, and the statistical decision is to FTR Ho. If we redo the test at ? = 0.05, our statistical decision would be: ---Select--- There is not enough information to make a decision at 0.05 FTR Ho at ? = 0.05 Reject Ho at...
