Exercise 4A sample of 150 boxes of cereal was randomly selected from the productionline and found to have a mean weight of 500g and a standard deviation of 20g.A week later a sample of 120 boxes was randomly selected and, this time, themean weight was 505g with a standard deviation of 16g.(a) Using Minitab, Construct a 95% confidence interval for the difference in the averageweight between the two samples.(a) With 95% confidence, would you conclude that the process has shifted or not?Explain your answer.

The first sample size is 150, with sample mean 500 g, and standard deviation 20 g. The second sample…

A study was carried out to compare the mean compressive strength of two types of concrete. 10 samples of each type of concrete were collected. Data (in psi) are presented in the next table. (The data table is in the picture) Assuming normality, determine a 95% confidence interval for the difference of the stockings and interpret it. Note: Solve what is requested step by step in order to arrive at the answer, do not skip steps.
The Accounting Department’s kaizen blitz team has spent 3 days analysing cycle time for processing invoice exceptions. While most invoices go through an Electronic Data Interchange (EDI) automated process, invoice exceptions follow a time-intensive manual process. Analyse the time (in minutes) it takes to process invoice exceptions. Suppose the population mean is known to be 42.8 minutes with a population standard deviation of 14.7 minutes. One random sample of n = 40 invoice exceptions had a sample mean of 44.783 minutes and a sample standard deviation of 15.584 minutes. Which of the following is the mean of the sampling distribution of the statistic X-bar?
A study compared the long-term results of two treatments: a modified Burch procedure, and a sling procedure for stress incontinence with a low-pressure urethra. Thirty-six women took part in the study with 19 in the Burch treatment group and 17 in the sling procedure treatment group. One of the outcome measures at three months post-surgery was maximum urethral closure pressure (cm H2O). In the Burch group the mean and standard deviation were 16.4 and 8.2 cm, respectively. In the sling group, the mean and standard deviation were 39.8 and 23.0, respectively. Construct the 99% confidence interval for the difference in mean maximum urethral closure pressure for the two populations represented by these subjects. What is the critical value of the confidence interval for difference in means? what is the lower bound of a 99% confidence interval for the difference in means? (Burch-Sling) what is the upper bound of a 99% confidence interval for the difference in means? (Birch-Sling)
A particular brand of tires claims that its deluxe tire averages at least 50,000 miles before it needs to be replaced. From past studies of this tire, the standard deviation is known to be 8,000. A survey of owners of that tire design is conducted. Of the 30 tires surveyed, the mean lifespan was 45,900 miles with a standard deviation of 9,800 miles. Using alpha = 0.05, is the data highly consistent with the claim? A-State the distribution to use for the test. (Round your answers to two decimal places.) B-What is the test statistic? (If using the z distribution round your answers to two decimal places, and if using the t distribution round your answers to three decimal places.) C-What is the p-value?

A random sample of 100 households was selected as part of a study on electricity usage, and the number of kilowatt-hours (kWh) was recorded for each household .The average usage was found to be 10.5 kWh. In a very large study in the previous year it was found that the standard deviation of the usage was 3.2 kWh. Assuming the standard deviation is unchanged and that the usage is normally distributed, calculate a 90% confidence interval for the mean usage (round to two decimals) a. (9.68 , 11.30) O b. (9.87 , 11.10) O c. (7.05 , 7.95) O d. None of these e. (9.97 , 11.00)
The average mpg usage for a 2017 Toyota Prius for a sample of 7 tanks of gas was 43.5 with a standard deviation of 1.8. For a 2017 Ford Fusion, the average mpg usage for a sample of 7 tanks of gas was 39.9 with a standard deviation of 2.0. Assuming equal variances, at α = .05, is the true mean mpg lower for the Ford Fusion? (a-1) Choose the appropriate hypotheses. H0: μtoy – μford ≤ 0 vs. H1: μtoy – μford > 0.

A random sample of 23 bags of apples (marked as 10 pounds each) received by a large grocery chain tested out as having a mean of 9.2 pounds with a variance of 2.56 pounds. Test whether the true mean of all bags is under 10 pounds. Set up hypotheses. Perform the appropriate test by showing your formula. Interpret the results using a Type I (alpha) error of .05. Also provide the p value here. Also construct a 95% confidence interval around your sample mean (X bar) that should contain the true mean (mu). Also interpret this interval.
The braking ability was compared for two car models. Random samples of two cars were selected. The first random sample of size 64 cars yield a mean of 36 and a standard deviation of 8. The second sample of size 64 yield a sample mean of 33 and a standard deviation of 8. Do the data provide sufficient evidence to indicate a difference between the mean stopping distances for the two models? Use Alpha= 0.01. Ho: µ1 – µ2 = 0 vs. Ha: µ1 – µ2 + 0 .p-value = 0.0017.
