Chapter 8 5. Toyota Motor Corporation developed the Scion car model to appeal to young consumers. Toyota claims the averag average age of the drivers was found to be 27.5 years. Assume the standard drivers is 2.3 years. e age of a Scion driver is 26 years old. Suppose a random sample of 18 Scion drivers was drawn, and the deviation for the age of Scion qsdo Construct a 95% confidence interval to estimate the average age of a Scion driver. Does this result lend support to Toyota's claim? What assumption needs to be made for this procedure? a. b. c. The US air traffic control system handled an average of 47,529 flights during 30 randomly selected days, The standard deviation for this sample is 6,210 flights per day. 6. t a 99% confidence interval to estimate the average number of flights per day handled by the a. Con struc system. tem can safely handle 50,000flights per day. What conclusion can be drawn with b. Suppose the current sys these results? What assumptions need to be made about this population? c. The US Department of Education reported that in 2007, 67% of stude within 12 months of graduating from high school. In 2013, a random sampl from high school 12 months prior was se college or a trade school. nts enrolled in college or a trade school e of 160 individuals who graduated lected. From this sample, 102 students were found to be enrolled in 7. estimate the actual proportion of students enrolled in colle Construct a 90% confidence interval to trade school with ge or a in 12 months of graduating from high school in 2013. n of error for this sample? a. idence that this proportion has changed since 2007?

Quadratic Equation

When it comes to the concept of polynomial equations, quadratic equations can be said to be a special case. What does solving a quadratic equation mean? We will understand the quadratics and their types once we are familiar with the polynomial equations and their types.

Demand and Supply Function

The concept of demand and supply is important for various factors. One of them is studying and evaluating the condition of an economy within a given period of time. The analysis or evaluation of the demand side factors are important for the suppliers to understand the consumer behavior. The evaluation of supply side factors is important for the consumers in order to understand that what kind of combination of goods or what kind of goods and services he or she should consume in order to maximize his utility and minimize the cost. Therefore, in microeconomics both of these concepts are extremely important in order to have an idea that what exactly is going on in the economy.
