QUESTION 6 An assumption made about the value of a population parameter is called a(n) Oa. hypothesis. Ob. probability. Oc error. Od. conclusion. QUESTION 7 A random sample of 50 students selected from WKU had an average GPA of 2.8 and a standard deviation of 0.95 points. Using the information from this sample, WKU's president wants to determine if the average GPA has significantly increased from its traditional 2.5. Assume the distribution of the GPAS across WKU is nomal. Given...
A range of values constructed from sample data so that the parameters occurs within that range at a specific probability is
Find the interval ??.,?41 within which 95 percent of the sample means would be expected to fall, assuming that each sample is from a normal population (a) ?-161,0-12, n-47. (Round your answers to 2 decimal places.) The 95% range is from -1,317, ?-21, n The 95% range is from to (b) 10, (Round your answers to 2 decimal places.) to (c) ?-70, ?-1, n-27. (Round your answers to 3 decimal places.) The 95% range is from to
For each problem, sketch all of the qualitatively different vector fields that occur as the parameter u is varied. Find the values of u at which bifurcation occur, and classify the bifurcations. Finally, sketch the bifurcation diagram or the steady states x* vs the parameter u. 1. ** = 5 – ļe-x? 2. espe= ux - T H > 0.
