Question

independent practice

1. the overall shape of this graph is
2. how many plants were 5 - 6 inches tall at the end of the experiment?
3. the graph peaks for which interval?
4. how many students are represented in the histogram?
5. the overall shape for this graph is
6. what percent of the total students who participated in the sale sold 21 - 25 candy bars?
7. how many players scored points in november?
8. what percent of the total players scored 31 - 40 points in november?

Explanation:

Step1: Find the total number of students

Add the number of students in each interval: \(4 + 6+6 + 8+12=36\)

Step2: Calculate the percentage for \(21 - 25\) candy - bars

The number of students in \(21 - 25\) is \(12\). Use the formula \(\text{Percentage}=\frac{\text{Number in interval}}{\text{Total number}}\times100\). So \(\frac{12}{36}\times100=\frac{100}{3}\approx33.3\%\)

Step3: Find the total number of players

Add the number of players in each interval: \(2 + 1+4 + 3=10\)

Step4: Calculate the percentage for \(31 - 40\) points

The number of players in \(31 - 40\) is \(4\). Use the formula \(\text{Percentage}=\frac{\text{Number in interval}}{\text{Total number}}\times100\). So \(\frac{4}{10}\times100 = 40\%\)

Answer:

1. For the "Candy Bars Sold by Students" histogram:

• The overall shape is skewed (right - skewed as the tail is on the higher - value side).
• Approximately \(33.3\%\) of students sold \(21 - 25\) candy bars.

1. For the "Points Scored - Basketball Team November" histogram:

• \(10\) players scored points in November.
• \(40\%\) of the total players scored \(31 - 40\) points.
