Question: The president of the American Insurance Association is interested in comparing the yearly cost of auto insurance offered by two leading companies. She randomly selected a sample of 12 families, some with only a single driver, others with several teenagers, and offered one free family car insurance policy to contact the two companies and ask for a price quote. In order to make the data comparable, certain features, such as the amount of the deductible, are standardized. The sample information is listed below:

a. At the 10% significance level, can we conclude that there is a statistically significant difference in the amount of quoted?

b. Determine the p-value in part (a) and interpret its meaning. Use Excel for your p-value.

c. Use SPSS and Microsoft Excel to solve this problem and compare the computer printout with your answers to previous parts.
