(g) Q1 = 0.25*n = 0.25*10 = 2.5 ~ 3rd value in the increasing order = 1.5
25% of the values are less than or equal to 1.5.
(h) Q1 = 0.75*n = 0.75*10 = 7.5 ~ 8th value in the increasing order = 5.0
75% of the values are less than or equal to 5.0.
(i) IQR = Q3 - Q1 = 5 - 1.5 = 3.5
The midlle 50th % value is 3.5.
(j) Min = 0.8
Q1 = 1.5
Q2 = 2.9
Q3 = 5
Max = 5.2

2. (25pts) Two different brands of latex (water-based) paint are being considered for use in a large construction project. To choose between the brands, one of the key factors is the time it takes the paint to dry. Engineers sampled 22 specimens of each brand and measured the drying times (in hours) of each specimen. The data collected are given in Table 1 below Specimen Brand A Brand B Specin Brand A Brand B 3.5 2.7 3.9 4.2 4.6 2.7...
