During the 1940s, in spite of a decrease in driving due to wartime restrictions on gasoline, spare parts, and tires, USAA grew rapidly and reported a profit of over $3 million. At the end of the 1950s, profits were over $14 million. In 1961, USAA’s bylaws were changed such that membership no longer had to be relinquished when an officer leaves the service.

A study by Quadrant Information Services commissioned by calculated auto insurance rates for each of the 50 states; and as a result, the average annual rate for the United States was $1317. Suppose annual rates of auto insurance in the United States are normally distributed with a standard deviation of $324. Based on these data, what is the probability that a randomly selected auto insurance rate in the United States would be greater than $1750? What percentage of auto insurance rates would be less than $1200?

Included in 3M’s more widely-known products are Scotch®Tape, Post-it®Notes, and Ace™ bandages. 3M was born as a small-scale mining company in 1902 when the five founders invested in harvesting a mineral known as corundum from a mine in Minnesota on the shores of Lake Superior. The mine ultimately did not produce much corundum, but the company used a spirit of innovation, collaboration, and technology to discover other materials and products that could be of use to consumers and companies. In 1910, the company, then known as Minnesota Mining and Manufacturing (3M), moved its headquarters to St. Paul where it is today. In the early 1920s, 3Mcreated the world’s first waterproof sandpaper which helped open up opportunities for the company in the automotive industry. In 1925, a young lab assistant invented masking tape thereby helping to diversify the company’s offering. Over the next few decades, many of the “scotch” products were developed and marketed including scotch tape, scotlite and Scotchgard. In the 1960’s, 3M introduced dry silver microfilm, photographic products, carbonless papers, overhead projection systems and numerous health care and dental products. In 1980, 3M introduced post its which created a new category in the marketplace. By the year 2000, there were new products such as post it super sticky pads, scotch transparent duct tape, optical films for LCD tvs and a family of new scotch brite cleaning products. In 209, they introduced a new line of stethoscopes and health care and introduced new products in the is grinding industry. In later years, 3M developed 3M solar mirror film 1100 for concentrated solar power. Today, 1/3 of 3M sales come from products invented within the past 5 yrs, during which time over 8 billion has been invested in R&D and related expenditures. According to company information, the global 3M team is committed to creating the technology and products that advance every company, enhance every home and improve every life. 3M has been listed on the dow jones sustainability index for 15 consecutive years.

This index care domains derived from 16 measures of key processes and outcomes that effectvalue in health care. According to 3M, this Value Index Score can increase the understanding f provider and system performance thereby accelerating and prioritizing the areas where improvement is needed. This measure can be used by both providers and payers to help improve patient outcomes and to control costs.Suppose you were asked to develop a sampling plan for a study to determine the value index, and general attitudes toward the index, what sampling plan would you use?What is the target population(or are there multiple target populations)?Which of the four types of random sampling discussed in the chapter would you use and why? If you were to use stratified random sampling, what would be your strata?———————————————————————————— Question #3: In a particular area of the Northeast, an estimated 75% of the homes use heating oil as the principal heating fuel during the winter. A random telephone survey of 150 homes is taken in an attempt to determine whether this figure is correct. Suppose 120 of the 150 homes surveyed use heating oil as the principal heating fuel. What is the probability of getting a sample proportion this large or larger if the population estimate is true?
