Trader Joe's is a privately held chain of specialty grocery stores in the United States. It has developed a reputation as a unique grocerystore selling products such as gourmet foods, beer and wine, bread, nuts, cereal, and coffee. One of their best-selling nuts is a 16-ouncepackage of Raw California Almonds. Since it is impossible to pack exactly 16 ounces in each packet, a researcher has determined thatthe weight of almonds in each packet is normally distributed with a mean and a standard deviation equal to 16.01 ounces and 0.08ounces, respectively.a. Discuss the sampling distribution of the sample mean based on any given sample size.b. Find the probability that a random sample of 20 bags of almonds will average less than 16 ounces.c. Suppose your cereal recipe calls for no less than 48 ounces of almonds. What is the probability that three packets of almonds willmeet your requirement?

Given:• The weight of almonds in each packet is normally distributed.• Mean weight (μ) = 16.01…

See pictures for graphics. Problem: Methadone is a synthetic drug whose effect on the body is similar to that of morphine and heroin. Methadone has been used to help people control their addictions to these other drugs. Recently, the governor of Florida vetoed a million-dollar appropriation for several Methadone clinics in the state. Had Methadone use gotten out of hand? The following is a histogram that summarizes information from a study of 25 Florida Methadone clinic patients. (Florida's projected mean daily dosage per Methadone clinic patient was about 100 milligrams.)

B. A manufacturing company is analyzing its accident record. The accidents fall into two categories: ➤Minor-dealt with by first aider: Average cost k50 ➤ Major-hospital required. Average cost k1,000 The company has 1,000 employees, of which 180 are office staff and the rest work in the factory. The analysis shows that 10% of employees have an accident each year and 20% of accidents are major. It is assumed that an employee has more than one accident in a year. (i) Determine the expected total cost of accidents in a year. On further analysis it is discovered that a member of office staff | half the probability of having an accident relative those in the factory. (ii) Show that the probability that a given a member of office staff has an accident in a year is 0.0549. (iii) Determine the probability that a randomly chosen employee who has had an accident is office staff.

Suppose a consumer affairs representative for Mars Incorporated claims that M&M’s plain chocolate candies are mixed such that each large production batch has the following percentages of colored candies: 20% brown, 20% yellow, 10% red, 20% orange, 10% green, and 20% blue. To test this claim, a professor distributed small sample bags of M&M’s to students and had them count the number of candies of each color. The counts of the students were then pooled with the following results. At α=0.05, determine whether there is sufficient evidence to conclude that the percentages are different from what the representative claims. Candy Colors Brown Yellow Red Orange Green Blue Number of candies 190 185 110 168 117 189 Copy Data Step 3 of 4 : Compute the value of the test statistic. Round any intermediate calculations to at least six decimal places, and round your final answer to three decimal places.
To boost holiday sales, Ginsberg jewelry store is advertising the following promotion: “If more than five inches of snow fall in the first three days of the year (January 1 through January 3), all purchases made between Thanksgiving and Christmas are free!” Based on historical sales records as well as experience with past promotions, the store manager believes that the total holiday sales between Thanksgiving and Christmas could range anywhere between $200,000 and $400,000 but is unsure of anything more specific. Ginsberg has collected data on snowfall from December 16 to January 18 for the past several winters in the file Ginsberg. Construct a simulation model to assess potential refund amounts so that Ginsberg can evaluate the option of purchasing an insurance policy to cover potential losses. What is the probability that Ginsberg will have to refund sales? What is the average refund? Why is this a poor measure to use to assess risk? In the cases when snowfall exceeds 5…

According to a report by the U.S. Environmental Protection Agency (EPA), containers and packaging generated about 34.6% of all municipal solid waste (MSW) in the country in a recent year. This was the largest category of such waste. The next highest group was nondurable goods, which accounted for 25.4 % of waste. This was followed by durable goods at 10.9%, yard trimmings/other at 13.4%, and food scraps at 15.7%. Suppose last year, one large midwestern U.S. city processed 303 (1,000 tons) of MSW broken down by waste type as follows: Waste Type Containers and Packaging Nondurable Goods Durable Goods Yard Trimmings/Other Food Scraps MSW (1,000 tons) 129 73 28 45 28 Determine if there is a significant difference between the distribution of municipal solid waste in this midwestern city and the distribution released by the EPA a.
