During one shift, the express lane clerk recorded how many times customers violated the "10 items or less" rule for his lane. In particular, he recorded how many items over the limit each violator placed on the conveyor belt. This data is summarized in the histogram below. NOTE: The last class actually represents "7 or more items," not just 7 items.**Histogram Explanation:**- The histogram has the x-axis labeled as "# items over 10" and the y-axis as "Frequency."- The data is divided into intervals, or "bins," each representing the number of items over the 10-item limit.- The first bin (0.5 to 1.5 items over) has a frequency of 6.- The second bin (1.5 to 2.5 items over) has a frequency of 8.- The third bin (2.5 to 3.5 items over) has a frequency of 11.- The fourth bin (3.5 to 4.5 items over) has the highest frequency at 12.- The fifth bin (4.5 to 5.5 items over) has a frequency of 10.- The sixth bin (5.5 to 6.5 items over) has a frequency of 8.- The last bin (6.5 to 7.5 items over, representing 7 or more) has a frequency of 5.What is the frequency of times the limit was exceeded by at least 3 items?**Answer Calculation:**To find the frequency of times the limit was exceeded by at least 3 items, add the frequencies from the third bin onward:11 (3.5) + 12 (4.5) + 10 (5.5) + 8 (6.5) + 5 (7.5) = 46**ans = 46**

Name 3) The Tire Rack, an online distributor of tires and wheels, conducts extensive testing to provide customers with products that are right for their vehicle, driving style, and driving conditions. In addition, the Tire Rack maintains an independent customer survey to help drivers help each other by sharing their long-term tire experiences (The Tire Rack website, August 1, 2016). The following data shows survey results (one to 10 scale with 10 being the highest rating) for 18 high performance all season tires. The variable tread wear rates quickness of wear based on drivers expectations, the variability dry traction rates the grip of a tire on a dry road, the variable steering rates the tires steering responsiveness, and the variable buy again rates the driver's desire to purchase the same tire again.
