QRB 501 – Week 4 Syllabus
I4 Two Sample T-Test Cell Phone Plastic Test
Fifteen cell phones were tested for crushing resistance. The measured variables are in pounds per square inch (PSI). The resistance of the first batch were recorded: 50, 36, 34, 45, 56, 42, 53, 25, 65, 33, 40, 42, 39, 43, 42. Another batch of 15 were measured after being heated to120 degrees Fahrenheit for six hours: 43, 44, 51, 40, 29, 49,39, 59, 43, 48, 67, 44, 46, 54, 64.
- Construct the research problem, question and purpose. Construct the null and alternative hypothesis. Use an alpha level of significance of .05.
- Do Descriptive Statistics on this data and describe the data in a write-up. Run Megastat, Hypothesis Tests, Compare Two Independent Groups, T-Test (Pooled Variance), Hypothesized Difference: Zero. Explain the differences. Conclude.
G4 Group
The Sacramento Medical center added a new wing. The plan was for the new wing to increase the average number of patients per day above the 25 average before the addition. The following data lists a random sample of 15 days with the number of patients. Did the plan work?
25, 27, 25, 26, 25, 28, 28, 27, 24, 26, 25, 29, 25, 27, 24.
