On Rhea's twitter account her tweets over the years have averaged about 35 likes per tweet with a standard deviation of 10. Several of here tweets have recently gone viral. Rhea's last 20 tweets have been averaging 50 likes per tweet with a standard deviation of 5. Rhea wants to know if her recent viral tweets are increasing her average likes. How do we use a Z-Test to test to calculate the data and determine if we reject or fail to reject the null hypothesis?
