Assignment for IHP525 Confidence Intervals
1. Weight of a newborn. A SRS is taken from a population of fullterm newborns in a research. In this demographic, the standard deviation of birth weights is 2 pounds. Calculate the 95 percent confidence intervals for the following samples:
a) The number of people is 81, and the weight is 7.0 pounds.
b) n = 9 with a weight of 7.0 pounds
c) Which sample yields the most accurate mean birth weight estimate?
d) Apply what you learned in step a to the CI you calculated.
2. Confidence interval and Pvalue The Pvalue of a twosided test of H0: = 0 is 0.03. Is there a chance that the 95 percent confidence interval for includes 0? Will 0 be included in the 99 percent confidence interval for? In each case, explain your reasoning.
3. The length of the menstrual cycle. The following are the menstrual cycle lengths (days) in an SRS of nine women: 31, 28, 26, 24, 29, 33, 25, 26, 28. Using a onesample ttest, see if the mean menstrual cycle length differs substantially from a lunar month. (There are 29.5 days in a lunar month.) Assume that the population’s values follow a Normal distribution. Consider a twosided option. Show all steps in the hypothesistesting process.
4. The length of the menstrual cycle. The mean length of menstrual periods in an SRS of 9 women was estimated in Problem 3. Days with a standard deviation of 2.906 days were discovered in the data.
a) For the mean menstrual cycle length, calculate a 95% confidence interval.
b) Is the mean menstrual cycle duration substantially different from 28.5 days at 0.05 (two sided) based on the confidence interval you just calculated? Is it statistically significant when compared to = 30 days at the samelevel? Give an explanation for your decision. (The relationship between confidence intervals and significance tests was discussed in Section 10.4 of your text.) Here, too, the same rules apply.)
Fluoridation of drinking water is a good example of this. The number of cavityfree children per 100 in 16 North American cities BEFORE and AFTER municipal water fluoridation schemes was investigated in a study. The data is listed in the table below. To utilize StatCrunch to calculate the needed information, you’ll have to manually type the data in.
a) For each city, calculate the delta values (After Before). Then plot the differences in a stemplot or boxplot. Interpret the plot of your story.
b) What percentage of cities saw an increase in the number of people without cavities?
c) Estimate the mean change with a 95% confidence interval (i.e. compute a 95 percent CI for the mean difference).

Content (worth a maximum of 50% of the total points) 
Zero points: Student failed to submit the final paper. 
20 points out of 50: The essay illustrates poor understanding of the relevant material by failing to address or incorrectly addressing the relevant content; failing to identify or inaccurately explaining/defining key concepts/ideas; ignoring or incorrectly explaining key points/claims and the reasoning behind them; and/or incorrectly or inappropriately using terminology; and elements of the response are lacking. 
30 points out of 50: The essay illustrates a rudimentary understanding of the relevant material by mentioning but not full explaining the relevant content; identifying some of the key concepts/ideas though failing to fully or accurately explain many of them; using terminology, though sometimes inaccurately or inappropriately; and/or incorporating some key claims/points but failing to explain the reasoning behind them or doing so inaccurately. Elements of the required response may also be lacking. 
40 points out of 50: The essay illustrates solid understanding of the relevant material by correctly addressing most of the relevant content; identifying and explaining most of the key concepts/ideas; using correct terminology; explaining the reasoning behind most of the key points/claims; and/or where necessary or useful, substantiating some points with accurate examples. The answer is complete. 
50 points: The essay illustrates exemplary understanding of the relevant material by thoroughly and correctly addressing the relevant content; identifying and explaining all of the key concepts/ideas; using correct terminology explaining the reasoning behind key points/claims and substantiating, as necessary/useful, points with several accurate and illuminating examples. No aspects of the required answer are missing. 
Use of Sources (worth a maximum of 20% of the total points). 
Zero points: Student failed to include citations and/or references. Or the student failed to submit a final paper. 
5 out 20 points: Sources are seldom cited to support statements and/or format of citations are not recognizable as APA 6^{th} Edition format. There are major errors in the formation of the references and citations. And/or there is a major reliance on highly questionable. The Student fails to provide an adequate synthesis of research collected for the paper. 
10 out 20 points: References to scholarly sources are occasionally given; many statements seem unsubstantiated. Frequent errors in APA 6^{th} Edition format, leaving the reader confused about the source of the information. There are significant errors of the formation in the references and citations. And/or there is a significant use of highly questionable sources. 
15 out 20 points: Credible Scholarly sources are used effectively support claims and are, for the most part, clear and fairly represented. APA 6^{th} Edition is used with only a few minor errors. There are minor errors in reference and/or citations. And/or there is some use of questionable sources. 
20 points: Credible scholarly sources are used to give compelling evidence to support claims and are clearly and fairly represented. APA 6^{th} Edition format is used accurately and consistently. The student uses above the maximum required references in the development of the assignment. 
Grammar (worth maximum of 20% of total points) 
Zero points: Student failed to submit the final paper. 
5 points out of 20: The paper does not communicate ideas/points clearly due to inappropriate use of terminology and vague language; thoughts and sentences are disjointed or incomprehensible; organization lacking; and/or numerous grammatical, spelling/punctuation errors 
10 points out 20: The paper is often unclear and difficult to follow due to some inappropriate terminology and/or vague language; ideas may be fragmented, wandering and/or repetitive; poor organization; and/or some grammatical, spelling, punctuation errors
