Potato Chip Quality Control. NDC Technology’s MM710e On-Line Snacks Gauge rapidly measures surface brownness of potato chips just before packaging. This allows for a high degree of control over this important characteristic of a potato chip; chips that are too brown are overfried, and chips that are not sufficiently brown are underfried. A potato chip manufacturer is now using the MM710e to assess the quality of the chips it produces; one of this manufacturer’s goals is to produce less than 1 overfried chip in every 1000 chips. In a recent random sample of 111,667 chips taken from the production lines of the manufacturer’s production facilities nationwide, the MM710e found 98 overfried chips. Conduct a hypothesis test to determine if the sample data indicates the manufacturer is meeting its goal for overfried chips at α = .05.

- George Samson is responsible for quality assurance at Integrated Electronics. Integrated Electronics has just signed a contract with a company in China to manufacture a control device that is a component of its manufacturing robotics products. Integrated Electronics wants to be sure that these new, lower-cost components meet its high-quality standards. George has asked you to establish a quality-monitoring process for checking shipments of control device A. The variability of the electrical resistance, measured in ohms, is critical for this device. Manufacturing standards specify a standard deviation of 3.6, and the population distribution of resistance measurements is normal when the components meet the quality specification. The monitoring process requires that a random sample of n = 6 observations be obtained from each shipment of devices and the sample variance be computed. Determine an upper limit for the sample variance such that the probability of exceeding this limit, given a…arrow_forwardYou may need to use the appropriate technology to answer this question. An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. The data obtained follow.

An outbreak in 2002 and 2003 killed 91 of the 95 gorillas in seven home ranges in the Congo. To study the spread of the virus, measure "distance" by the number of home ranges separating a group of gorillas from the first group infected. Here are data on distance and time in number of days until deaths began in each later group. (Data set may be found here.) Distance 1 3 4 4 4 5 Time 4 21 33 41 43 46 (a) Make a scatterplot.

- The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases.
