A recent study found that the average exercise time for adults in the United States is 20 minutes per day. It is believed that Silicon Valley (dubber as home to the talented and wealthy) emphasizes more on health and therefore, its residents exercise more than the national average of 2 minutes per day. We conducted a simple random sample of 33 adults in Silicon Valley and found that on the average they exercise 22.8 minute per day with a standard deviation of 9 minutes. Conduct an analysis to determine whether there is statistical evidence to show that Silicon Valley residents' average time exercised per day i greater than the national average. Provide the test statistic value from your analysis.

Question
A recent study found that the average exercise time for adults in the United States is 20 minutes per day. It is believed that Silicon Valley (dubbed as home to the talented and wealthy) emphasizes more on health and therefore, its residents exercise more than the national average of 20 minutes per day. We conducted a simple random sample of 33 adults in Silicon Valley and found that on the average they exercise 22.8 minutes per day with a standard deviation of 9 minutes. Conduct an analysis to determine whether there is statistical evidence to show that Silicon Valley residents' average time exercised per day is greater than the national average.
