SITY Suppose the boxplot below depicts the daily sales (in KD) for a sample of 260 days for a given retail store. A Note that: • B= 868 KD ● C= 1028 KD D = 1188 KD ● Questions: B - The distribution of the data is symmetric - The data depicted in the boxplot includes - How many days had sales above 1188 KD? D - What percentage of days had sales above 868 KD? KD + - What is the interquartile range (IQR) for this data? IQR = - What is the value of point E? days E * days % - The number of days that had sales between 868 KD and 1188 KD is days

Home Prices A real estate agent compares the selling prices of homes in two municipalities in a certain location to see if there is a difference. The results of the study are shown. Is there enough evidence to reject the claim that the average cost of a home in both locations is the same? Use a = 0.10.
