- What is a sample space?Outline and explain fully the procedures in testing hypothesis.Federal law requires that a jar of peanut butter that is labeled as containing 32 ounces must contain at least 32 ounces. An independent consumer advocate feels that a certain peanut butter manufacturer is shorting customers by under filling the jars so that the mean content is less than 32 ounces as stated on the label. The hypotheses tested are . a) In the context of this example, describe type I and type II errors. Give lots of details. b) If you owned the peanut better plant which type of error would you consider more serious (from a business point of view)? Explain, giving lots of details. c) Based on your answer to part b, should you choose α = 0.01 or α = 0.10?
- Expected value of the policy for the ins.company?An FDA inspector knows that the average amount of fecal matter particulate on a restaurant's kitchen sink can't be more than 5 ppm. On each day of the last week (7 days) she found the average amount of fecal matter on the kitchen sink at your favorite local restaurant to be: 6, 18, 2, 6, 5, 7 and 1. The inspector believes this restaurant is out of compliance. Run a hypothesis test to see if there is enough evidence to conclude that the average amount of Fecal Matter present exceeds the legal amount.Inferential statistics is the branch of statistics that draws conclusions about (answer) based on information from (answer).
- A bank recieve average 6 bad cheks per a day what is probabilty that bank recieve 4 bad cheks2. It is thought that a new process for producing a certain chemical may be cheaper than the currently used process. Each process was run 6 times, and the cost of producing 100L of the chemical was determined each time. The results, in dollars, were as follows: New Process: 51, 52, 55, 53, 54, 53Old Process: 50, 54, 59, 56, 50, 58 Can we conclude that the mean cost of the new method is less than that of the old method? Use a 0.01 level of significance.1. What does “empirical” mean as it applies to inferential statistics?
- Wages of workers Without a High School Diploma. SmartAsset reports that the average weekly earnings for workers who have not received a high school diploma are $493 in 2018. Suppose you would like to determine if the average weekly earnings for workers who have received a high school diploma is significantly greater than the average Supplementary Exercises 465 weekly earnings for workers who have not received a high school diploma. Data providing the weekly pay for a sample of 50 workers who have received a high school diploma are available in the file WeeklyHSGradPay. These data are consistent with the findings reported by SmartAsset. a.

Frito-Lay produces snack-sized bags of Doritos with 1.75-ounce bags. Unfortunately, Frito-Lay has received many complaints that the bags of chips lack the promised amount of chips. PepsiCo, the owner of Frito-Lay, decide to run an internal investigation of their Doritos chip production. They sample around 500 bags of chips to discover that they found an average of 1.59 ounces with a standard deviation of .12 ounces. Conduct a hypothesis test with an alpha-level of .05. Should they change their production of Doritos chips to match the 1.75 ounces on the bag?
