It is desired to determine if the means of two different processes differ. a) Perform a .05 level test assuming equal variances.

Ho: __________________ Test Statistic: _______________________ Ha: __________________ p-value: ___________________________

Conclusion: Fail to Reject Ho Reject Ho

b) Perform a .05 level test not assuming equal variances.

Ho: __________________ Ha: __________________

c) Perform a test for equal variances at the .05 level. Ho: __________________
Ha: __________________

Test Statistic: _______________________ p-value: ___________________________ Conclusion: Fail to Reject Ho Reject Ho

d) Which analysis will you use to determine if you have a difference in means? (a or b) ____________

g) What is your conclusion about a difference between the two means? Reject or Fail to Reject?

Conclusion: Fail to Reject Ho Reject Ho

You have been asked to determine if two different production processes have different mean numbers of units produced per hour. Process 1 has a mean defined as μ1 and process 2 has a mean defined as μ2. The null and alternative hypotheses are Upper H 0: μ1 − μ2 less than or equals ≤0 and Upper H 1 : mu 1 minus mu 2 greater than 0 H1: μ1−μ2>0. The process variances are unknown but assumed to be equal. Using...

You will perform a Two Sample Hypothesis Test for Means. For the Hypothesis Tests, make sure to report the following steps: Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Find the critical value(s) and identify the rejection region(s). Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original...

The company has three different processes to make the batteries. An experiment to determine the best process has been generated for the three processes. You are the quality engineer and must determine is one process is statically better than the other processes. You have selected 5 batteries from each process and they have been tested for the hours they “hold a charge.” The results of the hours are in the following table. Battery Manufacturing Processes Process A Process B Process...

Take the exchange rates of two different nations at two different time intervals and determine the DER and IER with reference to one country. Discuss the impact on import due to changes in the exchange rate upon any one nation. Also discuss the impact on export due to change in the exchange rate upon the same nation. Discuss the strength or weakness of one currency over the period of time with reference to other currency.
