A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 95% confident that his estimate is in error by no more than three percentage points? Complete parts (a) through (c) below.Question content area bottomPart 1a) Assume that nothing is known about the percentage of computers with new operating systems. n=enter your response here (Round up to the nearest integer.)Part 2b) Assume that a recent survey suggests that about 96% of computers use a new operating system.n=enter your response here (Round up to the nearest integer.)Part 3c) Does the additional survey information from part (b) have much of an effect on the sample size that is required?A.Yes, using the additional survey information from part (b) dramatically reduces the sample size.B.Yes, using the additional survey information…
Socially conscious investors screen out stocks of alcohol and tobacco makers, firms with poor environmental records, and companies with poor labor practices. Some examples of "good," socially conscious companies are Johnson and Johnson, Dell Computers, Bank of America, and Home Depot. The question is, are such stocks overpriced? One measure of value is the P/E, or price-to-earnings ratio. High P/E ratios may indicate a stock is overpriced. For the S&P Stock Index of all major stocks, the mean P/E ratio is ? = 19.4. A random sample of 36 "socially conscious" stocks gave a P/E ratio sample mean of x = 17.7, with sample standard deviation s = 5.2. Does this indicate that the mean P/E ratio of all socially conscious stocks is different (either way) from the mean P/E ratio of the S&P Stock Index? Use ? = 0.05. (a) What is the level of significance?State the null and alternate hypotheses. H0: ? = 19.4; H1: ? < 19.4H0: ? ≠ 19.4; H1: ? = 19.4 H0: ? = 19.4; H1: ? ≠ 19.4H0: ?…
Are cigarettes bad for people? Cigarette smoking involves tar, carbon monoxide, and nicotine (measured in milligrams). The first two are definitely not good for a person's health, and the last ingredient can cause addiction. Use the data in the table above to make a stem-and-leaf display for milligrams of tar per cigarette smoked. (Enter NONE in any unused answer blanks.) Are there any outliers? A. Yes, 1.0 may be an outlier. B. No, there are no outliers. C. Yes, 29.8 may be an outlier.
The bookstore at IRSC would like to estimate the proportion of students who prefer electronic textbooks (eBooks) over printed textbooks (hard copies). A random sample of 30 students was surveyed. Their preferences are listed below. eBook eBook eBook eBook eBook eBook eBook eBook eBook eBook eBook eBook eBook hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy hard copy Determine the point estimate, ① and the sample standard deviation, S. Round the sample proportion to four decimal places and round the standard deviation to six decimal places, if necessary. Sp Using a 97% confidence level, determine the margin of error, E, and a confidence interval for the proportion of all students at the college who work prefer eBooks over printed textbooks. Report the confidence interval using interval notation. Report the solutions in percent form, rounded to two decimal places, if necessary.…

A researcher wants to determine the percentage of American teenagers who send or receive text messages while doing homework. Which of the following techniques would likely be the MOST efficient way of obtaining an accurate estimate for this percentage? 1. Randomly select teenagers from the list of all teenage students in every state in America and mail surveys to those teens, asking them if they send or receive text messages while doing homework. 2. Send a survey to every teenager in America and ask them if they send or receive text messages while doing homework. 3. Randomly select teenagers from the list of all teenage students in one state and mail surveys to those teens, asking them if they send or receive text messages while doing homework.
