The standard error of the mean is 10.11 points
Step-by-step explanation:
Standard error of mean = t×sd/√n
sd = 115 points, n = 500, degree of freedom = n-1 = 500-1 = 499, assuming a 95% confidence level, t-value corresponding to 499 degrees of freedom and 95% confidence level is 1.96501
Standard error of mean = 1.96501×115/√500 = 10.11 points (to the nearest 100th)
