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
