**Fuel Efficiency Data Analysis**The following stem-and-leaf display represents the fuel efficiencies (in miles per gallon) for a sample of 17 new cars. Each entry's stem represents the tens digit, and the leaf represents the units digit.**Fuel Efficiency (miles per gallon)**```1 | 52 | 37773 | 01257794 | 195 | 0369```**Key:** 1 | 5 means a fuel efficiency of 15 miles per gallon.### Questions:**(a)** What is the lowest fuel efficiency in the sample overall? **(b)** What is the highest fuel efficiency in the 20s? **(c)** How many cars in the sample have fuel efficiencies in the 50s?This analysis forms the basis for interpreting the data set, assisting in identifying range, mode, and mean of the sample fuel efficiencies.

The stem-and-leaf for fuel efficiencies is 1523,7,730,1,2,5,7,7,941,950,3,6,9key:1|5 means a fuel…

Solve the problem. At the Jumping Jack cookie factory, quality assurance inspectors remove broken or otherwise defective cookies from a moving conveyor belt prior to packaging. Based on past studies, the plant manager knows that the inspectors eliminate 98% of the defective cookies at a conveyor belt speed of 9 feet per minute. As the belt speed increases, the factory can produce more cookies per hour, but at the cost of lower quality of the packaged product. Inspectors collect only 60% of defective cookies at a belt speed of 18 feet per minute.
