number of points

1. how many players scored points in november?
2. what percent of the total players scored 31 - 40 points in november?

Explanation:

Step1: Analyze "Plant Height Experiment"

For the plant - height histogram:

1. To find the number of plants 5 - 6 inches tall, we look at the height of the bar corresponding to the 5 - 6 inches interval. The bar height is 2.

Step2: Analyze "Video Games Owned by Students"

1. The graph peaks at the 6 - 8 games interval as it has the highest bar with a height of 12.
2. To find the total number of students, we sum the heights of all bars: \(4 + 6+12 + 8+4=34\).

Step3: Analyze "Candy Bars Sold by Students"

1. The overall shape of the candy - bar histogram is right - skewed as the tail extends to the right.
2. First, find the total number of students who participated in the sale: \(4 + 6+6 + 8+12=36\). The number of students who sold 21 - 25 candy bars is 12. The percentage is \(\frac{12}{36}\times100\%\approx33.3\%\).

Step4: Analyze "Points Scored - Basketball Team"

1. To find the number of players who scored points in November, sum the heights of all bars: \(2+1 + 4+3=10\).
2. The total number of players is 10. The number of players who scored 31 - 40 points is 4. The percentage is \(\frac{4}{10}\times100\% = 40\%\).

Answer:

1. For "Plant Height Experiment": 2 plants were 5 - 6 inches tall.
2. For "Video Games Owned by Students":

• The graph peaks for the 6 - 8 interval.
• 34 students are represented.

1. For "Candy Bars Sold by Students":

• The overall shape is right - skewed.
• Approximately 33.3% of students sold 21 - 25 candy bars.

1. For "Points Scored - Basketball Team":

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