The mean is: The median is: The sample standard deviation is: The first quartile is: The third quartile is: What percent of the respondents have at least 10 pairs of Shoes? 43% of all respondents have fewer than how many pairs of Shoes?\fFor a 4-unit class like Statistics, students should spend average of 12 hours studying for the class. A survey was done on 29 students, and the distribution of total study hours per week is bell-shaped with a mean of 14 hours and a standard deviation of 3.2 hours. Use the Empirical Rule to answer the following questions. a) 68% of the students spend between hours and hours on Statistics each week. b) 95% of the students spend between hours and hours on Statistics each week. c) 99.7%% of the students spend between hours and hours on Statistics each week.Here is a frequency distribution table (FDT) for a small data set: data value frequency 20 13 21 15 22 14 23 28 W 24 18 Find the following measures of central tendency. mean () = 22.2 X (Please show your answer to one decimal place.) median = 44 X (Please enter an exact answer.) mode = 23 (Please enter an exact answer. )
