8. a) The mean of 6 different plots of acidic soil samples is 3.2. An extra it with pH value 3.9 is included in the sample. What is the new mean? plot b) Five soil samples have a mean of 12 dS/m for soil electrical conductivity (EC). When a soil sample was removed, the mean is 11 dS/m. What is the value of the soil EC been removed? 9. Loss of calcium is a serious problem for older women. At the beginning of a study on the influence of exercise on the rate of loss, the amounts of bone mineral content in the radius bone of the dominant hand of 11 elderly women were: 0.88, 1.06, 0.90, 1.06, 0.79, 0.80, 0.85, 0.91, 0.94, 1.00, 0.72 Calculate: (a) The mean. (b) The median. (c) The mode. (d) A researcher says: "The mode seems to be the best average to represent the data in this survey." Give ONE reason to support this statement.

Question

Transcribed Image Text:8. a) The mean of 6 different plots of acidic soil samples is 3.2. An extra
plot with pH value 3.9 is included in the sample. What is the new mean?
b) Five soil samples have a mean of 12 dS/m for soil electrical conductivity
(EC). When a soil sample was removed, the mean is 11 dS/m.
What is the value of the soil EC been removed?
9. Loss of calcium is a serious problem for older women. At the beginning
of a study on the influence of
exercise on the rate of loss, the amounts of bone mineral content in the
radius bone of the dominant hand
of 11 elderly women were:
0.88, 1.06, 0.90, 1.06, 0.79, 0.80, 0.85, 0.91, 0.94, 1.00, 0.72
Calculate:
(a) The mean.
(b) The median.
(c) The mode.
(d) A researcher says: "The mode seems to be the best average to represent
the data in this survey." Give ONE reason to support this statement.
