Use the following information to answer questions 4, 5, 6, and 7. A manufacturer claims that the average calling range (in feet) for its 2.4−GHz cordless telephone is different than that of its leading competitor. You perform a study using 35 randomly selected phones from the manufacturer and 32 randomly selected similar phones from its competitor. The results are shown in the table below. 4. Set up the null and alternative hypotheses to test the manufacturer's claim. (a) He:μ1=μ2 versus Hα:μ1=μ2 (b) H0:μ1≥μ2 versus He:μ1<μ2 (c) H0:μ1≤μ2 versus Ha:μ1>μ2 (d) H0:x1≤x2 versus H2:x1>x2 (e) H0:μ1≥μ2 versus Hα:μ1=μ2 5. Find the value of the standardized test statistics. 6. Find the associated p-value to the test statistics. 7. State your decision and conclusion at α=0.05 :
