A hypothesis test is to be performed for a population proportion. For the given sample data and null hypothesis, compute the value of the test statistic, z = P-PO √ Po (1 - Po)/n 16) A radio show producer believes that a new proposed format would be preferred by only 25% of their current listeners. A survey of 100 current listeners showed that 17 favored the new format. Find the test statistic z and test the claim Ho: p = 0.25. Use a significance level a = .05. A) z=-2.439, Reject Ho C) z=-1.848, Reject Ho B) z=-2.439, Fail to Reject Ho D) z = -1.848, Fail to Reject Ho
