A sampling distribution (dotplot) for the mean quiz score for a sample n = 30 of STAT101 students is shown below. It was constructed using random samples from population data. If we take a random sample of 30 STAT101 students and calculate its sample mean, approximately what is the chance that we will see a sample mean above 74? (Hint: there are 1000 sample statistics represented in the dotplot.)
