Explanation / Answer

46)

Median of the given numbers is 53.2

To find Q3, we consider numbers to the right of median i.e. 55, 55, 67, 74

Q3 = (55 + 67)/2 = 61 (Option B)

47)

P16 is the 16th percentile

P(n+1)/100 = 16(30+1)/100 = 4.96

Round the position to the nearest integer. So if you round to 5 you get P16 = 6.1 (option A)

48)

Sally's body temperature = 98.20 + 2.4*0.62 = 99.688 (Option C)

49)

midpoint of first class = (52-50)/2 = 51 (Option A)

50)

Boundries of first class 49.5-52.5 (Option C)
