Explain the basic idea for performing a hypothesis test, based on independent samples, to compare two populations. Choose the correct answer below. A. Take random samples from the two populations under consideration. Calculate the sample proportions. Reject the null hypothesis if the proportions differ by more than the confidence level. B. Take random samples from the two populations under consideration. Calculate the sample proportions. Reject the null hypothesis if the proportions differ by too much. O C. Estimate the population proportion for each population under consideration. Calculate the expected difference between the population proportions. Reject the null hypothesis if the expected difference is too large. D. Estimate the population proportion for each population under consideration. Calculate the expected difference between the population proportions. Reject the null hypothesis if the expected difference is larger than the confidence level.
