2. A coffee shop relocates to Italy and wants to make sure that all lattes are consistent.They believe that each latte has an average of oz of espresso. If this is not the case, theymust increase or decrease the amount. They took a random sample of 10 lattes andthefollowing are the ounces of espresso 5,6,7,8,9,11,12,15,16,18.Use alpha 0.05Step 1: State the hypotheses Step 2: The level of significance, one/two-tailed test, degrees of freedomStep 3: Statistical TestStep 4: ComputationStep 5: Decision RuleStep 6: Reject H, or Failed to Reject HoStep 7: Conclusion

From the given information we conduct Hypothesis test.

A manufacturing company glues one part to another part during the assembly of its final product. Either too much or too little glue presents a problem. It is important for the pressure of the glue nozzle (pounds per square inch) to be set correctly because it affects the amount of glue (ounces) that is applied. Ten applications are sampled and the following information collected: SSXX = 129.6 SSYY = 2.345 SSXY = 16.6 X bar = 25.2 Y bar = 2.05 What is the estimated y intercept?
Check to see if there is a “glass ceiling”. Is a person’s career level dependent on their gender? a. Use the appropriate statistical test using the data below. Use the 0.05 alpha level. include the p-value and summarize your results. Career level/gender Entry level Manager level Director level Executive level Total Female 218 50 30 2 300 Male 290 60 40 10 400 b. Even if you do not get a significant result for part a of this problem, run a test to determine if the percentage of female executives is significantly less than the percentage of male executives. Use the 0.05 alpha level. include the p-value and summarize your results.
