A pickle producer currently purchases lids for its jars from a certain manufacturing company. The pickle producer has received a bid from a rival manufacturingcompany that will sell the lids at a very low price. The lids must have a diameter of approximately 3.5 inches, and because the lids must fit securely, the pickleproducer requires that the lids purchased have a standard deviation of no more than 0.02 inches. The rival company claims that it meets these specificationsand has supplied the pickle producer with 36 lids on a sample basis. The pickle producer's quality control department has constructed the following histogram,based on the sample of lids, to show to company executives:Frequency1515-1210+6.5-3.543.48Diameter of lid (in inches)3.463.53.52Based on this histogram, estimate the standard deviation of the sample of 36 diameters.Carry your intermediate computations to at least four decimal places, and round your answer to at least three decimal places.3:56 PM3/21/2022

The reading speed of second grade students in a large city is approximately normal, with a mean of 91 words per minute (wpm) and a standard deviation of 10 wpm. Complete parts (a) through (f).
The maximum allowable mean level of a toxin in smelters, herbicide production facilities, and other places where the toxin is used is 0.005 milligrams per cubic meter of air. Suppose smelters at two plants are being investigated to determine whether they are meeting standards. Two analyses of the air are made at each plant, and the results are shown below. A claim is made that the standard is being violated at Plant 2 but not at Plant 1. Do you agree? Assume α=0.05.

Two researchers conducteda study where the main goal wasto estimate the population meanfor a particular variable. Both researchers obtained a random sample from the population, and both obtained a sample standard deviation of s= 20. Researcher A selected a random sample of n= 100 individuals, whereas Researcher B selected a random sample of n= 64 individuals. Compute and report the standard error of the mean that Researcher A would obtain. Compute and report the standard error of the mean that Researcher B would obtain.
A company manager plans to purchase a machine. The company requires a high quality machine. The manager is currently considering two companies that supply this machine. The machine from company A can produce approximately1050 units in average per day, but the standard deviation of this machine is about 250 units per day; while the machine from company B can produce approximately 900 units in average per day, but the standard deviation of this machine is about 100 units per day. Both of these two companies guarantee at least 10 years life. In addition, both prices are similar although machine A is a little bit higher. Price is not the main concern for the manager because both prices are under their budget. However, the manager cannot decide which machine should be purchased, because he is not sure what test he needs to conduct. Can you recommend the manager what test the manager should conduct? Should the manager conduct the test about the difference between two population means or the…
The State Department of weights and measures is responsible for making sure that commercial weighing and measuring devices,such as scales, are accurate so customers and businesses are not cheated.Periodically,employees of the department go to businesses and test their scales. For example,a dairy bottles milk in 1-gallon containers. Suppose that if the filling process is working correctly,the mean volume of all gallon containers is 1 gallon with a standard deviation equal to 0.10 gallons.Based on this information, if the department employees selects a random sample of n = 9 containers,what is the probability that the mean volume for the sample will be greater than 1.01 gallons?
A certain company intends to market a weight-loss pill. They test it on a group of 2000 volunteers but splitting the group into one set of 1000 people who are given pill A for three months, and the second set of 1000 people, who are given pill B for the same three months. The results after 3 months are that the pill A set of people lost on average 10 pounds with a standard deviation of 6 pounds, while the pill B set of people lost an average of 43 pounds with a standard deviation of 9 pounds. What is the confidence level that pill B functions better than pill B for helping people to lose weight? Pill B is more effective than pill A at helping people to lose weight with a confdence level of %. 714
A man who moves to a new city sees that there are two routes he could take to work. A neighbor who has lived there a long time tells him Route A will average 5 minutes faster than Route B. The man decides to experiment. Each day he flips a coin to determine which way to go, driving each route 20 days. He finds that Route A takes an average of 45 minutes, with standard deviation 3 minutes, and Route B takes an average of 49 minutes, with standard deviation 5 minutes. Histograms of travel times for the routes are roughly symmetric and show no outliers. Complete parts a and b. (...) a) Find a 95% confidence interval for the difference between the Route B and Route A commuting times, (µÂ ¯ µÃ) - The confidence interval is (.). (Round to two decimal places as needed.)
A cereal manufacturer wants to test the performance of one of the packaging filling machines in his factory. This machine is designed to fit an average of 15 ounces of cereal into each box, and manufacturers want to detect any deviation from this setting. This quality study is conducted by taking a random sample of 100 boxes from today's production, and then determining whether the average content of all samples is the correct 15 ounces per box. From the sample obtained an average result of 14.85 ounces with a standard deviation of 0.55 ounces. Test the hypothesis for this study using = 2%
The instruction manual for an IKEA bookshelf claims that it will take 2 people 41 minutes to assemble. A local college student has started a business assembling IKEA furniture. He claims that as an individual it takes him less than 41 minutes to assemble the bookshelf. He examines 38 of his randomly selected bookshelf assembly times and finds that his average was 40.9 minutes with a standard deviation of 2.3 minutes. What can be concluded at the the αα = 0.10 level of significance? Round all answers to 3 decimal places where possible. The null and alternative hypotheses would be: test statistic: p value:
