The Odum Institute for Research in Social Science at the University of North Carolina made available data on all births that occur in the state of North Carolina. John Hokcomb of Cleveland State University selected a random sample of 500 births in the year 2005. Both weights can be modeled with a normal distribution with mean 3300 grams, or about 7.275 pounds. Consider finding a confidence interval for the mean age among all fathers of newborn babies in North Carolina in 2005. Varying the confidence level, three confidence intervals turn out to be: 90 %: (29.49, 30.56) 95%: (29.38, 30.66) 99 %: (29.18, 30.86) value for a significance test of whether the population mean age among these fathers differs from a. Based on these confidence intervals, what can you say about the 30 years? Explain value for testing Holi 30 vs Because the value HD – 30 is contained in all three of the given confidence intervals, you know that the one sided Hai > 30 is greater than 0.10 value for testing Hill – 30 vs. Because the value Ho – 30s contained in all three of the given confidence intervals, you know that the two-sided
Because the value Ho 30 is contained in all three of the given confidence intervals, you know that the one-sided p-value for testing Ho: = 30 vs. Haid >> 30 is greater than 0.10 – 30 vs. Because the value Ho – 30 is contained in all three of the given confidence intervals, you know that the two-sided p-value for testing Ho Hain > 30 is greater than 0.10 30 vs. Because the value Ho 30 is contained in all three of the given confidence intervals, you know that the one-sided p-value for testing Hoi H: 30 is greater than 0.10 ill – 30 vs. Because the value Ho – 30 is contained in all three of the given confidence intervals, you know that the two-sided p-value for testing H Hai 30 is greater than 0.05. ill – 30 vs. Because the value Ho – 30 is contained in all three of the given confidence intervals, you know that the two-sided p-value for testing H 3 0 is greater than 0.10 H
Because the value Ho – 30 is contained in all three of the given confidence intervals, you know that the two-sided p-value for testing Hill H: H 30 is greater than 0.10 s b. Based on your answer to part a, summarize your conclusion from the test and value. There is convincing evidence that the population mean age of all North Carolina fathers in 2005 differs from 30 years. There is convincing evidence that the population mean age of all North Carolina fathers in 2005 is greater than 30 years. Oo oo There is convincing evidence that the population mean age of all North Carolina fathers in 2005 is less than 30 years There is no convincing evidence that the population mean age of all North Carolina fathers in 2005 differs from 30 years.
