Assume two independent random samples are available which provide sample proportions. for the first sample assume n1= 100 and x1= 39. for the second sample, assume n2= 100 and x2= 49. test the null hypothesis that the population proportions are equal versus the alternative hypothesis that the proportions are not equal at the 90% confidence level. frame the test statistic by subtracting the proportion for population 1 from that for population 2. pick an appropriate z value, p-value and conclusion. round your answer to the nearest thousandth. group of answer choices
