3.1 And 3.2 Quiz Review: Histograms And Cumulative Relative Frequency Plots

The correct answer is 25% because it implies that only a quarter of college students have less than $1000 in debt. This suggests that the majority of college students have more than $1000 in debt, which is a common financial burden for many students.

The correct answer is 75% because the question is asking for the percentage of basketball players who are below 77 inches tall. Since the answer options are given in increasing order, we can deduce that 75% is the correct answer as it falls between 50% and 100%. This means that 75% of basketball players are shorter than 77 inches.

The statement "What percent of patients stay 14 days?" implies that all patients stay for 14 days. Therefore, the correct answer is 100%, indicating that all patients stay for 14 days.

The answer is 3 because the question asks for the number of cherry trees that fall between 60 and 65 feet tall. This means that we are looking for the number of cherry trees that have a height greater than 60 feet but less than 65 feet. Since there are 3 options (2, 3, and 4) that fall within this range, the correct answer is 3.

The correct answer is 75%. This means that 75% of the employees are below the age of 50. This can be calculated by subtracting the percentage of employees above the age of 50 from 100%. Since there are no options given for employees above the age of 50, it can be inferred that 25% of the employees fall into this category. Therefore, 100% - 25% = 75% of the employees fall below age 50.

50% of basketball players fall below a height of 74 inches. This means that half of all basketball players are shorter than 74 inches.

The most black cherry trees fall between the class of 75-80. This means that the majority of black cherry trees have a size measurement that falls within the range of 75 to 80.

The correct answer is 25% because it is the only option that represents a percentage below 40. The other options (50%, 75%, and 100%) are all higher percentages and therefore cannot be the correct answer.

The correct answer is 50%. This means that half of the patients stay for 2 days. The other options, 25%, 75%, and 100%, are not correct because they do not represent half of the patients.

The units on the vertical axis in this case are frequency. This means that the values represented on the vertical axis are measurements of how often a particular event or phenomenon occurs.

The correct answer is 75% because it is the highest percentage given and implies that a significant majority of patients stay for 4 days.

The correct answer is 45. The median age is the middle value in a set of ages arranged in ascending order. In this case, the ages are 60, 55, 50, and 45. When arranged in ascending order, the median age is the middle value, which is 45.

The units on the horizontal axis are feet. This means that the values plotted on the horizontal axis represent measurements in feet.

The above histogram has 6 classes because there are 6 distinct bars or columns representing different ranges or intervals of data. Each bar represents a class or category, and there are a total of 6 bars in the histogram.

The answer "about 84%" suggests that a significant majority (approximately 84%) of the employees fall below the age of 55. This means that only a small percentage of employees are aged 55 or above.

Based on the given information, 75% of the college students surveyed have less than $2000 of debt.

The statement "100%" means that all of the college students surveyed have less than $5000 in debt. This implies that none of the surveyed students have a debt amount equal to or greater than $5000.

The class width refers to the range of values that are included in each class interval. In this case, the class width is 5, which means that each class interval will cover a range of 5 units. For example, if the first class interval is 0-4, the next class interval will be 5-9, and so on.

The interquartile range is a measure of statistical dispersion, specifically the difference between the upper quartile and the lower quartile. In this case, the upper quartile is $3000 and the lower quartile is $2000, so the interquartile range is $1000.

The correct answer is $1500. This is the median credit card debt because it is the middle value when the debts are arranged in ascending order. The other options, $3000, $2000, and $500, are higher or lower than the median value, making them incorrect.

The given answer, 31, suggests that there were 31 black cherry trees in the original data set. This is the most likely explanation as it directly corresponds to one of the options provided.

The interquartile range is a measure of statistical dispersion, specifically the range between the first quartile (Q1) and the third quartile (Q3) in a dataset. It represents the spread of the middle 50% of the data and is useful for identifying outliers and determining the variability within a dataset. In this case, the correct answer is 3 because it falls between the first and third quartiles.

The interquartile range is a measure of statistical dispersion, representing the range between the first quartile and the third quartile. In this case, the interquartile range is 6 inches because it is the difference between the first quartile (5 inches) and the third quartile (11 inches).

The interquartile range is a measure of the spread or dispersion of a dataset. It is calculated by subtracting the value of the first quartile from the value of the third quartile. In this case, the first quartile is 10 and the third quartile is 20, so the interquartile range is 10. This means that the middle 50% of the data falls within a range of 10 units.

The correct answer is 2 because the median is the middle number in a set of numbers when they are arranged in ascending or descending order. Since there are only four options given, the median would be the second number, which is 2.
