Question 1

The pie chart shows the percentage of votes received by each candidate in the student council presidential election. Use
the pie chart to answer the question.
-A two-pound bag of assorted candy contained 100 caramels, 83 mint patties, 93 chocolate squares, 80 nut clusters, and 79 peanut butter taffy pieces. To create a pie chart of this data, the angle for the slice representing each candy type must be computed. What is the degree measure of the slice representing the mint patties rounded to the nearest degree?
A) $69 ^ { \circ }$
B) $19 ^ { \circ }$
C) $5 ^ { \circ }$
D) $52 ^ { \circ }$

Accepted Answer

The total number of candies is 435. The percentage of mint patties is $ \frac{83}{435} \times 100 \approx 19.08\% $. The angle for the mint patties is $ \frac{83}{435} \times 360 \approx 68.62^\circ $, which rounds to $69^\circ$.

-What is the difference between a bar chart and a histogram
A) The bars on a bar chart do not touch while the bars of a histogram do touch.
B) The bars in a bar chart may be of various widths while the bars of a histogram are all the same width.
C) The bars in a bar chart are all the same width while the bars of a histogram may be of various widths.
D) There is no difference between these two graphical displays.

Accepted Answer

A bar chart represents categorical data with spaces between the bars to emphasize that each bar is a separate category, whereas a histogram represents continuous data with bars touching to indicate the continuous nature of the data.

\hline
\end{array}$
A) $0.06$
B) $0.059$
C) $0.408$
D) $0.4$

Accepted Answer

The class width is the difference between the upper limit of one class and the lower limit of the next class. For example, from the first class (0.7585-0.8184) to the second class (0.8185-0.8784), the difference is 0.8185 - 0.7585 = 0.06. This is consistent across all classes, indicating a class width of 0.06.
