Recent research has found that 10% of Americans aged 30-49 played tennis in the past 12 months. A local city wishes to test whether this is true in their city as well. If more than 10% of their residents aged 30-49 play tennis, improvements will be made on their tennis courts. A random survey of 200 residents aged 30-49 found that 48 played tennis. Do we have evidence that more than 10% of the residents play tennis? Use α=.05.
