Sample questions asked in the 5th edition of Statistics:
Answer the following questions: x 3 4 5 7 8 y 4 6 7 12 14 (a) What are the estimates of ? 0 and ? 1 ? (b) Compute the standard error, the point estimate for ? . (c) Assuming the residuals are normally distributed, determine . (d) Assuming the residuals are normally distributed, test H 0 : ? 1 = 0 versus H 1 : ? 1 ? 0 at the ? = 0.05 level of significance.
Technically, we assume that we are obtaining simple random samples from infinite populations when obtaining sampling distributions. If the size of the population is finite, we technically need a finite population correction factor. However, if the sample size is small relative to the size of the population, this factor can be ignored. Explain what an “infinite population” is. What is the finite population correction factor? How small must the sample size be relative to the size of the population so that we can ignore the factor? Finally, explain why the factor can be ignored for such samples.
Use the given table, which lists six possible assignments of probabilities for tossing a coin twice, to answer the following questions. Sample Space Assignments HH HT TH TT A 1111 4 4 4 4 B 0 0 0 1 C 3 5 5 3 16 16 16 16 D 1111 2 2 2 2 E 1111 4 4 4 8 F 12 2 4 9 9 9 9 Which of the assignments of probabilities should be used if the coin is known to always come up tails?
Temperatures It is well known that San Diego has milder weather than Chicago, but which city has more deviation from normal temperatures over the course of a month? Use the following data, which represent the deviation from normal high temperatures for each day in October 2010. In which city would you rather be a meteorologist? Why? DEVIATION FROM NORMAL HIGH TEMPERATURE, CHICAGO (°F) 8 13 19 6 ?9 7 ?13 ?7 11 11 0 0 1 ?9 15 ?2 ?5 2 ?17 ?5 22 1 ?4 8 ?15 2 17 ?3 6 7 ?2 DEVIATION FROM NORMAL HIGH TEMPERATURE, SAN DIEGO (°F) 4 ?6 ?2 ?3 ?3 ?3 ?6 5 ?1 ?1 ?5 ?4 10 1 ?2 ?1 ?5 ?5 8 ?4 3 ?4 ?4 ?3 4 ?5 7 ?5 ?6 ?4 ?6
Hungry or Thirsty? How much time do Americans spend eating or drinking? Suppose for a random sample of 1001 Americans age 15 or older, the mean amount of time spent eating or drinking per day is 1.22 hours with a standard deviation of 0.65 hour. Source: American Time Use Survey conducted by the Bureau of Labor Statistics (a) A histogram of time spent eating and drinking each day is skewed right. Use this result to explain why a large sample size is needed to construct a confidence interval for the mean time spent eating and drinking each day. (b) In 2010, there were over 200 million Americans age 15 or older. Explain why this, along with the fact that the data were obtained using a random sample, satisfies the requirements for constructing a confidence interval. (c) Determine and interpret a 95% confidence interval for the mean amount of time Americans age 15 or older spend eating and drinking each day. (d) Could the interval be used to estimate the mean amount of time a 9-year-old American spends eating and drinking each day? Explain.
Hypertension In a random sample of 678 adult males 20 to 34 years of age, it was determined that 58 of them have hypertension (high blood pressure). Source: The Centers for Disease Control. (a) Obtain a point estimate for the proportion of adult males 20 to 34 years of age who have hypertension. (b) Construct a 95% confidence interval for the proportion of adult males 20 to 34 years of age who have hypertension. Interpret the confidence interval. (c) You wish to conduct your own study to determine the proportion of adult males 20 to 34 years old who have hypertension. What sample size would be needed for the estimate to be within 3 percentage points with 95% confidence if you use the point estimate obtained in part (a)? (d) You wish to conduct your own study to determine the proportion of adult males 20 to 34 years old who have hypertension. What sample size would be needed for the estimate to be within 3 percentage points with 95% confidence if you don’t have a prior estimate?
Chegg Staff Review of the Textbook:
Statistics Informed Decisions Using Data 5e by Michael Sullivan, III, by virtue of its easy understandability vis-à-vis content, is a brilliant source of information for intermediate level to postgraduate level students, who want to gain a better understanding on classification of data, graphs, interpretation of results, and more. Further, small projects related to Chi-square test, estimation of parameters, tests on hypothesis for large samples and small samples, and building regression models using the concepts with dummy variables could be done by reading the book.
The layout of the book, inclusive of the font size and running heads is easy to read and understand, wherein the concepts are given with detailed explanations and with enough graphs and diagrams, which helps readers to understand the principles and ideas easily.
The book contains the basic concepts of statistics, such as descriptive statistics, which contain organizing qualitative and quantitative data and graphical presentation of data, measures of central tendency, measures of dispersion, and more. This book also contains initial concepts of grouped and ungrouped data. The concepts of probability and probability distributions of discrete and continuous data are discussed with examples and exercises.
Also, the estimation of parameters, hypothesis tests by comparing two means, three means (ANOVA), inferential statistical techniques, different sampling methods, confidence intervals, and prediction intervals are explained in a lucid and succinct manner. Example problems, diagrams, and graphs which are meticulously placed in the book enhance readers’ comprehension.
Readers will further find advanced topics, such as “least squares regression model” and “multiple regression”, “interaction and dummy variables”, “building regression models”, “non-parametric statistical tests”, and more.
This book is also helpful for students from different disciplines, such as psychology, social sciences, and management students which strengthen the ability to classify and analyze data.
The textbook has several exercises for students to practice. At the end of each chapter, under the title “Assess your Understanding”, a large set of questions are given for readers to deliberate. At a staggering 795 pages, statistical tables, answers to ‘odd-exercise questions’, and answers to review exercises are all given. The book also contains effective sampling methods. Readers will surely be able to deduce and comprehend the formulas and exercises using Excel, Minitab, or even a calculator. There are plenty of review-type questions to give readers the opportunity to practice problems.
