Apply critical value (rejection region) method for the following Hypothesis testing of a single population mean:Null Hypothesis Ho: ? = 200Alternative Hypothesis H1: ? ? 200 (Two-Tailed test)In a random sample of 100 subjects, the sample mean found to be x? =220.Population standard deviation is ?=50. Significance level is ? = 0.10Calculate test statisticsFor the given significance level ? = 0.10, find critical valuesDraw the line for z-scale and use critical values to identify rejection region (shade these portions)Mark position of test statistics on your z-scale.Does test statistics fall in the rejection region?Will you reject or do not reject Ho?Do you want a similar Paper?
