4. Assume that the average time for an adult to run 1 mile is 9,72 minutes, with a standard deviation of 0.75. A researcher measured the time for adults who were physically active, but did not previously run, to complete a 1 mile run and compared it to the population values. The average from the sample of 36 adults was 7.89 minutes. Calculate Cohen's d as a measure of effect size. Give your answer accurate to two decimal places. 4.
