The size of each plot is 3630 square feet to plant six vegetables.
Given, Susan is using 0.5 acres of land.
we know that 1 acre = 43,560 square feet
0.5 acre = 1/2 acre = 1/2 × 43,560
= 21780 square feet.
we need to divide the land into 6 equal sized plots.
divide 21780 into six equal parts.
= 21780/6
= 3630 square feet
the land is being divided into 3630 square feet to plant 6 equal sized plots.
Hence susan plants six vegetables in 3630 square feet each.

For normal distribution it means that 4 bags represent 16 % of all samples.
4 bags ------ 16%
x bags ------ 100 %
---------------------------
4 * 100 = x * 16
16 x = 400
x = 400 : 16
x = 25
Answer: 25 bags were probably taken as samples.
