2 | 35
3 | 26
4 | 1
5 | 2257
6 | 045
7 | 0456789

b) The relative frequency histogram as attached diagram.
As shown, the plot is skewed to the left.
c)
i) mean = 62.7
ii) median = 72
iii) Standard deviation = 24.87923
Step-by-step explanation:
a) The first approach is to sort the data in ascending or descending order. Next, we Identify the minimum grade and the maximum grade. We then list the stems based on the minimum and maximum. And we construct the stem and leaf diagram as show. The first digit represents the stem and the last digit represents the leaf.
As shown, all the grade are two digits value, with minimum as 06 and maximum as 98. In this case, the first stem is 0 and the last stem is 9.
Others (b & c) are just the usual calculations.
<span>d=20,009 + 0.15n
</span>$22,100 = 20,009 + 0.15n
$2091 = 0.15n
n = 2091/.15 = 13940
1 cup milk= 1 3/4 cup flour
1 cup flour=3/7 cup cocoa
4cups milk= 4x 1 3/4=7 cups flour
7 cups flour= 7x3/7= 3 cups cocoa
So the answer would be 3 cups of Cocoa
The square root of 82 falls in between 9 and 10
