The population of college students using “normal shoes” is able to complete a particular racecourse in an average of 250 seconds. The standard deviation for this population is 20 seconds and the population is normally distributed. A random sample of 28 college students is given a special pair of new shoes and asked to run the course. The average “race time” for this group is 243 seconds. The designer of the shoes feels his shoes should alter the race times of those individuals who use them. If we double the sample size are the results statistically significant? What happens with the effect size? Provide necessary values and explain in detail.
