Suppose Starbucks would like to determine if the median age of its customers is 42. The ages of 50 randomly sampled customers were recorded in the following table.
Customer’s Age Number of Customers
Below 42 ............ 30
Equal to 42 ............ 4
Above 42 ............ 16
Using α = 0.10, perform a hypothesis test to determine if the median age of Starbucks customers is 42.
