A recent poll found that 664 out of 1026 randomly selected people in a particular country felt that colleges and universities with big sports programs placed too much emphasis on athletics over academics. Assuming the conditions for the CLT are met, use the accompanying Minitab output to complete parts a and b below. N Event Sample p 95% CI for p 1026 664 0.647173 (0.617934, 0.676413) Question content area bottom b. Suppose a sports blogger wrote an article claiming that a majority of adults from this country believe that colleges and universities with big sports programs place too much emphasis on athletics over academics. Does this confidence interval support the blogger's claim? Explain your reasoning. A. No, it is not a plausible claim because the confidence interval contains 50%. B. No, it is not a plausible claim because the confidence interval does not contain only values above 50%. C. Yes, it is a…

Perform the indicated Goodness of fit test. Among the five northwestern states, Washington has 45% of the population, Oregon has 25% , Idaho has 15%, Montana has 10% and North Dakota has 5%. A market researcher selects a sample of 100 subjects with 37 in Washington, 20 in Oregon, 18 in Idaho, 18 in Montana and 7 in North Dakota. Use a significance level of 0.05 to test the claim that the sample of 100 subjects has a distribution that agrees with the distribution of the state populations a) Hypothesis: b) Decision c) Conclusion

The widths of contact windows in certain CMOS circuit chips have a design specification of 3.5 μm (see Phadke et al., The Bell System Technical Journal, 1983, for details.) Postetch window widths of test specimens were as follows: 3.21, 2.49, 2.94, 4.38, 4.02, 3.82, 3.30, 2.85, 3.34, 3.91 Can we reject the hypothesis that the design specification is being met, at the 5% significance level? What assumptions are necessary for this test to be valid?l
