Complete parts (a) through (c) below. Click the icon to view the table of water usage. a) Taking into account the number of buildings surveyed, draw a histogram of the data. Identify the mode of the histogram. Choose the correct histogram below. 50- Number of Buildings Number of Buildings JA OB 40 80 120 160 200 O- 40 80 120 160 200 Water Usage (L/ft^2/yr) Water Usage (L/ft^2/yr) Number of Buildings Number of Buildings OC OD 40 80 120 160 200 40 80 120 160 200 Water Usage (L/ft^2/yr) Water Usage (L/ft^2/yr) The mode of the histogram is b) Using the midpoint of each range, and assuming that the average water use of buildings over 200- Lift 2 - is 300 _/ft yr yr , estimate the mean and the standard deviation of the water usage of the office buildings surveyed. The mean is. (Round to two decimal places as needed.) The standard deviation is. (Round to two decimal places as needed.) c) Using the midpoint of each range, calculate the quartiles and median of this data. Identify how many buildings are outliers. The median is. (Type an integer or a decimal. Do not round.) The lower quartile (Q1) is. (Type an integer or a decimal. Do not round.) The upper quartile (Q3) is (Type an integer or a decimal. Do not round.) There is/are outlier(s). "Type a whole number.)
