In order to compare the means of two populations, independent random samples of size400 observations are selected from each population with the following results:Sample 1Sample 2Sample Mean = 5275Sample Mean = 5240S1= 150S2 200n1= 400n2 =400Assume equal variances for the populations. To test the null hypothesis Ho: H1-H2 = 0 versus thealternative hypothesisH H1-2=O at the 0.05 level of significance, the most accurate statement isO The value of the test statistic is 3.29 and the critical value is +1.645O The value of the test statistic is 3.29 and the critical values are +1.645 and -1.645The value of the test statistic is 2.80 and the critical values are +1.645 and -1.645O The value of the test statistic is 2.80 and the critical value is +1.96O The value of the test statistic is 2.80 and the critical values are +1.96 and -1.96

Three different methods for assembling a product were proposed by an industrial engineer. To investigate the number of units assembled correctly with each method, 30 employees were randomly selected and randomly assigned to the three proposed methods in such a way that each method was used by 10 workers. The number of units assembled correctly was recorded, and the analysis of variance procedure was applied to the resulting data set. The following results were obtained: SST =10,890; SSTR =4600. a. Set up the ANOVA table for this problem (to 2 decimals but p-value to 4 decimals, if necessary).

An automobile manufacturer claims that their van has a 50.5 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this van. After testing 101 vans they found a mean MPG of 50.1 with a variance of 4 MPG. Is there sufficient evidence at the 0.1 level that the vans have an incorrect manufacturer's MPG rating? State the null and alternative hypotheses for the above scenario. Answer Ho H₂ Tables Keypad Keyboard Shortcuts
Over the years, a sushi restaurant has had a mean customer satisfaction rating of 72.5 with a variance of 24.7. The owner has hired you to perform a hypothesis test to see if using a new menu will have any effect on the variance, o“. To do so, you survey a random sample of 19 customers who ordered from the new menu. For the customers surveyed, the variance of ratings is 44.3. Under the assumption that the customer ratings using the new menu follow a normal distribution, you will perform a chi-square test. Find x, the value of the test statistic for your chi-square test. Round your answer to three or more decimal places.
Two different brands of milk are randomly sampled, and the fat content in each bottle is determined. Twenty-six bottles of Brand A yielded an average fat content of 26 grams with a standard deviation of 5 grams, and 31 bottles of Brand B yielded an average fat content of 25.8 grams with a standard deviation of 7 grams. Test the hypothesis at the 10% level of significance that the variances are different.

An electronic company's records show that the mean number of circuit.boards rejected per batch is 5.7 with a variance of 1.4. Due to a change in the molding process, factory management has hired you to perform a hypothesis test to check if the variance, o, has increased. To do so, you test a random sample of 10 batches produced using the new process; the number of circuit boards rejected per batch has a sample variance of 2.5. Under the assumption that the number of circuit boards rejected per batch using the new process follows a normal distribution, you will perform a chi-square test. Find x, the value of the test statistic for your chi-square test. Round your answer to three or more decimal places. * = 0

Three different methods for assembling a product were proposed by an industrial engineer. To investigate the number of units assembled correctly with each method, 36 employees were randomly selected and randomly assigned to the three proposed methods in such a way that each method was used by 12 workers. The number of units assembled correctly was recorded, and the analysis of variance procedure was applied to the resulting data set. The following results were obtained: SST = 12,120; SSTR = 4,540.

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 7.6 parts/million (ppm). A researcher believes that the current ozone level is not at a normal level. The mean of 1313 samples is 7.2 ppm with a variance of 0.49 Assume the population is normally distributed. A level of significance of 0.02 will be used. Make the decision to reject or fail to reject the null hypothesis.
Given two independent random samples with the following results: n1=12x‾1=73s1=27n1=12x‾1=73s1=27 n2=12x‾2=102s2=22n2=12x‾2=102s2=22 Use this data to find the 95%95% confidence interval for the true difference between the population means. Assume that the population variances are equal and that the two populations are normally distributed. Step 1 of 3 : Find the point estimate that should be used in constructing the confidence interval.
On the basis of data provided by a Romac Salary survey, the variance in annual salaries for seniors in public accounting firms is approximately 2.1 and the variance in annual salaries for managers in public accounting firms is approximately 11.1. The salary data were provided in thousands of dollars. Assuming that the salary data were based on samples of 25 seniors and 26 managers, test the hypothesis that the population variances in the salaries are equal. At a 0.05 level f significance, what is your conclusion? use excel please
A carpenter is making doors that are 2058 millimeters tall. If the doors are too long they must be trimmed, and if they are too short they cannot be used. A sample of 61 doors is made, and it is found that they have a mean of 2044 millimeters with a variance of 729. Is there evidence at the 0.05 level that the doors are either too long or too short? State the null and alternative hypotheses for the above scenario.
