It is known from past experience that the population variance of hourly visits is 3000. You decide to design and run an appropriate hypothesis test to determine if the Facebook ads will generate enough traffic to qualify your Streaming for the bonus. use alpha = .07 The test you design is as follows Ho: U=320 Ha: U>320 Reject Ho if Z > Z (.07) What is the probability that your test will commit a type two error, if the true mean number of hourly channel visits generated by running Facebook ads is actually 321 hits per hour?
