37: Is a parallelagram
38 Is Not
39: Is
We would expect 2 people to come down with the flu.
We multiply the probability, 35%, by the number of people exposed, 5:
0.35*5= 1.75 ≈ 2
Firstly, put Derek and Paul's collection together:
1950, 1952, 1908, 1902, 1955, 1954, 1901, 1910, 1929, 1935, 1928, 1930, 1925, 1932, 1933, 1920
1950+1952+1908+1902+1955+1954+ 1901+1910+1929+1935+1928+1930+ 1925+ 1932+1933+1920
=30864
=30864÷16
=1929
∴the mean is 1929.
Median:
1901, 1902, 1908, 1910, 1920, 1925, 1928, 1929, 1930, 1932, 1933, 1935,
1950, 1952, 1954, 1955
1930÷1929
=1.0005184
= Median
Range:
1955-1901
=54
∴the range is 54.
Step-by-step explanation:
Start with the average. (of your data set)
Find how much each data value deviates from the average (difference of average and data value).
Take the absolute value of each difference.
Add all of these absolute values.
Divide by the total number of data values.
