Description: Car Sales A car salesman records the number of cars he sold each week for the past year. The following frequency histogram shows the results. (a) What is the most frequent number of cars sold in a week? (b) For how many weeks were two cars sold? (c) Determine the percentage of time two cars were sold. (d) Describe the shape of the distribution. GRAPH CANT COPY

Key Concepts

Relative Frequency and Percentage

Relative frequency involves finding the proportion of the total number of observations that fall within a certain category or interval. By converting these relative frequencies into percentages, the data can be expressed in terms of the percentage of the total, offering an easy way to compare and understand the prevalence of different outcomes.

Frequency Histogram

A frequency histogram is a graphical representation that organizes a group of data points into user-specified ranges. It shows how frequently each range of values occurs within a data set, making it easier to visualize the distribution, spot trends, and identify any outliers or unusual patterns.

Mode

The mode is a measure of central tendency that indicates the most frequently occurring value or interval in a data set. In the context of a histogram, it corresponds to the highest bar representing the data point or range with the maximum frequency.

Distribution Shape

The shape of a distribution refers to the overall pattern or outline formed by the plotted frequencies in a histogram. It can be symmetric, skewed to the right (positive skew), skewed to the left (negative skew), or bimodal/multimodal, providing insight into the nature of the data and underlying trends.
