A company manufactures printers and fax machines at plants located in Atlanta, Dallas, and Seattle. To measure how much employees atthese plants know about quality management, a random sample of 6 employees was selected from each plant and the employees selectedwere given a quality awareness examination. The examination scores for these 18 employees are shown in the following table. The samplemeans, sample variances, and sample standard deviations for each group are also provided. Managers want to use these data to test thehypothesis that the mean examination score is the same for all three plants.Plant 1AtlantaPlant 2 Plant 3DallasSeattle847259747464827462777470717076868659Sample797565meanSamplevariance35.231.645.6Samplestandarddeviation5.935.626.75Set up the ANOVA table for these data.

Sir pls stepwise and i only need e) part. Pls correct with explanation.
The commercial for the new Meat Man Barbecue claims that it takes 14 minutes for assembly. A consumer advocate thinks that the assembly time is lower than 14 minutes. The advocate surveyed 12 randomly selected people who purchased the Meat Man Barbecue and found that their average time was 13.5 minutes. The standard deviation for this survey group was 2.1 minutes. What can be concluded at the the a = 0.01 level of significance level of significance? You may assume the data are normally distributed.
The average wait time to get seated at a popular restaurant in the city on a Friday night is 13 minutes. Is the mean wait time less for men who wear a tie? Wait times for 16 randomly selected men who were wearing a tie are shown below.

One of the advantages of understanding statistics is that you can apply the concepts to yourself. This is even easier to do during our present time because of the widespread use of wearables. Wearables are accessory devices or clothing with embedded technology that are worn by a person and used to provide feedback to the person wearing them. Examples include the Fitbit, which is worn on the wrist and gathers data such as number of steps walked, heart rate, sleeping time. Another example is Ambiotex's smart shirt which is designed for athletes and has sensors in the shirt to measure heart rate, anaerobic threshold, fitness and stress levels. There are other companies making similar products. Suppose that you are interested in the amount of sleep you get a night. Sleep is very important and there is evidence that many Americans do not get enough sleep. You hypothesize you get 6 hours of sleep a night. Using a wearable, you track your amount of sleep on 16 random nights. Test the…

How would a person set up the hypotheses if they wanted to test the claim: the mean temperature of a October day in Oahu is different from 81 degrees? A: Ho µ = 81° vs HA H > 81° B: Ho H = 81° vs HA H 81° A
The average American consumes 85 liters of alcohol per year. Does the average college student consume less alcohol per year? A researcher surveyed 13 randomly selected college students and found that they averaged 82.1 liters of alcohol consumed per year with a standard deviation of 23 liters. What can be concluded at the the a = 0.10 level of significance? You may assume the data are normally distributed.
