Once you have collected the mean, standard deviation and number of respondents of a survey, you must take additional steps, which are listed below. Please order the answers in the appropriate order Question 5 options: Take the population's standard deviation and multiply by 1.96, producing the span value Ask ourselves if the null hypotheses value can be found within the confidence interval. If the answer is yes, we accept the null hypotheses, otherwise we reject it. Add and subtract the span to the mean of the sample, giving us the range of possible values for the population mean. Calculate the population standard deviation by dividing the sample's standard deviation by the sample's total number of respondents
