Extracted text: In the first virtual quiz in the Stat 111 class last academic year with only 14 students, the following scores(X values) were obtained, out of 10: 3, 4, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 8, 9. Using the population coefficient of kurtosis based on the fourth moment, what type of kurtosis is present in this distribution? Answer LEPTOKURTIC, MESOKURTIC, or PLATYKURTIC. Write the computed value, rounded to one decimal place, beside your first answer, separated by a comma. Note: The following sums can be computed from the data: £*, X; = 84, E, X} = 536, E, X? = 3,600, E X$ = 25,256. The population variance can be computed as 14 =1 N²
