A local bank claims that the waiting time for its customers to be served is the lowest in the area. A competitor bank checks the waiting times at both banks. The sample statistics are listed below. Test the local bank's claim. Use the information given below. Use a significance level of .05 and assume the variances are equal. Sample statistics for a local bank and a competitor's bank Local Bank Competitor Bank Sample size = 46 = Iu n2 = 50 Average waiting time in minutes for each x. = 2.3 mins. sample X2 = 2.6 Sample Standard Deviation of each Sample 1.1 mins S2 = 1.0 mins.

What is meant by the sample space of an experiment?
Two types of flares are tested and their burning times (in minutes) are recorded. Summary statistics are given below.Brand Xn=35x = 19.4 mins = 1.4 min Brand Yn=40x = 15.1 mins = 0.8 min Use a 0.08 significance level to test the claim that the two samples are from populations with the same mean. Use the traditional method or the P Value method of hypothesis testing.
An operations manager with General Motors corporate offices wishes to determine if the true mean productivity of employees at its Detroit, Michigan plant is different from its Opel/Vauxhall Plant in Bochum, Germany. For this analysis, productivity will be measured by the number of cars that employees assemble per day. Random samples of employees in Detroit and Bochum are selected, and the productivity scores at each assembly plant are recorded. The following results are obtained. t-Test: Two-Sample Assuming Equal Variances Detroit Bochum Mean 58.5 54.3 Variance 42 56 Observations 13 13 Pooled Variance XX Hypothesized Mean Difference 0 df XX t Stat XXXXX P(T<=t) one-tail XXXXX t Critical one-tail XXXXX P(T<=t) two-tail XXXXX t Critical two-tail XXXXX Using a significance level of…
Two machines (A and B) are used to fill plastic bottles with liquid laundry detergent. By default, the variability of liquid filled should be in a normal distribution form and both machines should operate similarly. If there is any difference, they may need to be calibrated. The output below shows the production result obtained from 14 bottles of Machine A and 12 bottles of Machine B: LOOK TO THE 2 HOPTPS. Q) At the 10% significance level, test whether calibration need to be made or not.
Explain the circumstances under which we would need to pool the variance for an independent samples t-test
A factory wanted to study the efficiency of three machines. whether there is a difference or not in terms of manufacture of bearings if there is a difference will have to adjust the new machine from collecting the diameter of the cartridge Bearing results are as follows: Perform a variance analysis to study whether the diameter of the bearings manufactured by three machines Is there a difference? (Use a significance level of 0.05) and perform Tukey's multiple comparisons if necessary.
For a statistics class project, a college student randomly samples 75 men who exercise at a gym regularly and 68 women who exercise at a gym regularly. The college student records the number of minutes each person exercises in a given week. The college student believes that the mean number of minutes per week is lower for men than for women. The college student conducts a hypothesis test at the 5% significance level. What conclusion can you draw from the output? The data provide sufficient evidence to reject the null hypothesis and to conclude that the mean number of minutes exercised per week is lower for men than for women. The data provide sufficient evidence to conclude that there is no difference in the mean number of minutes exercised per week for men and women. The data do not provide sufficient evidence to conclude that the mean number of minutes exercised per week is lower for men than for women. We accept the null hypothesis, and conclude that there is a difference in…
