Go Bananas!
Great Grasslands Grains, Inc.(GGG) manufactures and sells a wide variety of breakfast cereals.GGG's product development lab recently created a new cereal that consists of rice flakes and banana-flavored marshmallows. The company's marketing research department has tested the new cereal extensively and has found that consumers are enthusiastic about the cereal when 16-ounce boxes contain at least 1.6 ounces and no more than 2.4 ounces of the banana-flavored marshmallows.
As GGG prepares to begin producing and selling 16-ounce boxes of the new cereal, which it has named Go Bananas!, management is concerned about the amount of banana-flavored marshmallows. It wants to be careful not to include less than 1.6 ounces or more than 2.4 ounces of banana-flavored marshmallows in each 16-ounce box of Go Bananas!Tina Finkel,VP of Production for GGG, has suggested that the company measure the weight of banana-flavored marshmallows in a random sample of 25 boxes of Go Bananas! on a…
An aircraft emergency locator transmitter (ELT) is a device designed to
transmit a signal in the case of a crash. The Altigauge Manufacturing
Company makes 80% of the ELTS, the Bryant Company makes 15% of
them, and the Chartair Company makes the other 5%. The ELTS made
by Altigauge have a 4% rate of defects, the Bryant ELTS have a 6% rate
of defects, and the Chartair ELTS have a 9% rate of defects (which helps
to explain why Chartair has the lowest market share).
i)
If an ELT is randomly selected from the general population
of all ELTS, find the probability that it was made by the
Altigauge Manufacturing Company.
If a randomly selected ELT is then tested and is found to be

defective, find the probability that it was made by the
Altigauge Manufacturing Company.

- Cholesterol Cholesterol in human blood is necessary, but too much can lead to health problems. There are three main types of cholesterol: HDL (high-density lipoproteins), LDL (low-density lipoproteins), and VLDL (very low-density lipoproteins). HDL is considered “good” cholesterol; LDL and VLDL are considered “bad” cholesterol. A standard fasting cholesterol blood test measures total cholesterol, HDL cholesterol, and triglycerides. These numbers are used to estimate LDL and VLDL, which are difficult to measure directly. Your doctor recommends that your combined LDL/VLDL cholesterol level be less than 130 milligrams per deciliter, your HDL cholesterol level be at least 60 milligrams per deciliter, and your total cholesterol level be no more than 200 milligrams per deciliter. (a) Write a system of linear inequalities for the recommended cholesterol levels. Let x represent the HDL cholesterol level, and let y represent the combined LDL VLDL cholesterol level. (b) Graph the system of inequalities from part (a). Label any vertices of the solution region. (c) Is the following set of cholesterol levels within the recommendations? Explain. LDL/VLDL: 120 milligrams per deciliter HDL: 90 milligrams per deciliter Total: 210 milligrams per deciliter (d) Give an example of cholesterol levels in which the LDL/VLDL cholesterol level is too high but the HDL cholesterol level is acceptable. (e) Another recommendation is that the ratio of total cholesterol to HDL cholesterol be less than 4 (that is, less than 4 to 1). Identify a point in the solution region from part (b) that meets this recommendation, and explain why it meets the recommendation.arrow_forwardAn experimenter wants to study the relationship between type of milk and infant growth in underdeveloped countries.

- A restaurant forecasts 150 guests for a given period of time. The menu mix typically shows that 19% of guests order chicken skewers and 23% order rib-eye steak. Both are served with baked potato and steamed broccoli florets. The chicken breast, which needs to be trimmed and cut into cubes, has a 91% yield. Guests are served a 5 oz portion of the chicken (pre-cooked weight). The steak, on the other hand, comes in completely trimmed, portioned, and ready-to-cook. Broccoli is served as a 4 oz portion and has a 38% yield. Using this information, calculate how 159 many pounds of AP chicken breast and broccoli must be ordered. Also calculate how many units of steak and baked potato must be ordered to serve the guests during this time period. (None of these ingredients are used for any other dishes.)arrow_forwardA health officer is trying to study the malaria situation of Zambia. From the records of seasonal blood survey (SBS) results he came to understand that the proportion of people having malaria in Zambia was 3.8% in 2015. The size of the sample considered was 15,000. He also realized that during the year that followed (2016), blood samples were taken from 10,000 randomly selected persons. The result of the 2016 seasonal blood survey showed that 200 persons were positive for malaria.

- Critics of television often refer to the detrimental effects that all the violence shown on television has on children. However, there may be another problem. It may be that watching television also reduces the amount of physical exercise, causing weight gains. A sample of 15 10-year-old children was taken. The number of pounds each child was overweight was recorded (a negative number indicates the child is underweight). In addition, the number of hours of television viewing per week was also recorded. These data are listed here.

- Because of safety considerations, in May 2003 the Federal Aviation Administration (FAA) changed its guidelines for how small commuter airlines must estimate passenger weights. Under the old rule, airlines used 180 pounds as a typical passenger weight (including carry-on luggage) in warm months and 185 pounds as a typical weight in cold months. A journal reported that an airline conducted a study to estimate average passenger plus carry-on weights. They found an average summer weight of 183 pounds and a winter average of 190 pounds. Suppose that each of these estimates was based on a random sample of 100 passengers and that the sample standard deviations were 18 pounds for the summer weights and 21 pounds for the winter weights. n USE SALT (a) Construct a 95% confidence interval for the mean summer weight (including carry-on luggage) of this airline's passengers.
