Suppose that a report by a leading medical organization claims that the healthy human heart beats an average of 72 times per minute. Advances in science have led some researchers to question if the healthy human heart beats an entirely different amount of time, on average, per minute. They obtain pulse rate data from a sample of 85 healthy adults and find the average number of heart beats per minute to be 76, with a standard deviation of 13. Before conducting a statistical test of significance, this outcome needs to be converted to a standard score, or a test statistic. What would that test statistic be? (Use decimal notation. Give your answer to one decimal place.)

Question
Suppose that a report by a leading medical organization claims that the healthy human heart beats an average of 72 times per
minute. Advances in science have led some researchers to question if the healthy human heart beats an entirely different
amount of time, on average, per minute. They obtain pulse rate data from a sample of 85 healthy adults and find the average
number of heart beats per minute to be 76, with a standard deviation of 13. Before conducting a statistical test of significance,
this outcome needs to be converted to a standard score, or a test statistic. What would that test statistic be?
