The executives at HyGreat, a soda and energy drink company, conducted a quarterly review of the company's production facilities. For the review, the number of work stoppages due to mechanical failure were counted at each of the company's bottling plants. The histogram below summarizes the data. Use the histogram to answer each of the questions. Frequency (Number of bottling plants) 10- 9. 8. 7 6- 5. 4. 3. 2- 1 4 to 10 11 to 17 18 to 24 25 to 31 32 to 38 Number of work stoppages (a) One class is the most frequent. How many bottling plants are in this class? (b) What is the class width? (c) How many bottling plants had 17 or fewer work stoppages?
You need to use Stata to look up the dataset and its variables. Use Stata Companion Textbook. (Dataset: NES. Variables: spend8, [pw=nesw].) The NES dataset contains spend8, which records the number of government policy areas where respondents think spending should be increased. Scores range from 0 (the respondent does not want to increase spending on any of the policies) to 8 (the respondent wants to increase spending on all eight policies). The NES, of course, polls a random sample of U.S. adults. In this exercise you will analyze spend8 using the mean and lincom commands. You then will draw inferences about the population mean. (Remember to specify nesw as the probability weight.) The spend8 variable has a sample mean of ______. Make sure you use [pw=nesw] so your results are nationally representative. There is a probability of .95 that spend8’s true population mean falls between a score of ______ at the low end and a score of ______ at the high end. A student researcher…
A clerk entering salary data into a company spreadsheet accidentally put an extra "o" in the boss's salary, listing it as $1,000,000 instead of $100,000. Explain how this error will affect these summary statistics for the company payroll. Choose the correct answer: O Assuming the boss's true salary is above the median, the median will stay the same. The mean will be too large. O The median and the mean will be too large. O The median will be too small and the mean will be too large. O Assuming the boss's true salary is above the median, the median will be the same. The mean will be too small. Choose the correct answer: O The IQR will likely stay the same. The standard deviation will be too large. O The IQR will likely be too large. The standard deviation will be too small. O The IQR will likely be too large. The standard deviation will be too large. O The IQR will likely be too small. The standard deviation will bg too small.
Pain medications sometimes come with side effects. One side effect is dizziness. A researcher wanted to determine if some pain medications produced more or less dizziness than others. The results from his study are shown in the table below. Use a test to determine if the proportion of people within each treatment group who experienced dizziness are the same at the � = .01 level of significance. Tordol Placebo Naproxen Tylenol Advil Dizziness 83 32 36 5 8 No dizziness 4063 1832 1330 382 337 1) Determine the null and alternative hypotheses.

The college physical education department offered an advanced first aid course last summer. The scores on the comprehensive final exam were normally distributed, and the z-scores for some of the students are shown below. Robert 1.24 Juan 1.66 Haley −1.84 Joel 0.00 Jan −0.84 Linda 1.68 Which of these students scored above the mean? (Select all that apply.) Which of these students scored on the mean? (Select all that apply.) Which of these students scored below the mean? (Select all that apply.) If the mean score was μ = 140 with standard deviation σ = 15, what was the final exam score for each student?
Jocelyn believes that the amount of sleep she tends to get on weekends differs from the amount of sleep she tends to get during the school week. To investigate this claim, she randomly selects 10 weekend days and 10 school days. She consults her smart watch to determine the number of hours she slept for each of the selected days. Here are the data. School week: 7, 7.5, 8, 6.5, 8, 7.5, 7, 6.5, 7, 8Weekend: 9.5, 9.5, 8.25, 8.5, 7.5, 10.25, 8, 7, 9.5, 10 Jocelyn would like to determine if these data provide convincing evidence that the true mean amount of sleep she gets on the weekend differs from the true mean amount of sleep she gets during the school week. She tests H0: μS – μW = 0, Ha: μS – μW ≠ 0, where μW = the true mean amount of sleep Jocelyn gets on the weekend and μS = the true mean amount of sleep she gets during the school week. The conditions for inference are met. What are the values of the test statistic and P-value for a t-test about a difference in means? Find the…
A sample of 5 students were asked how much money they were carrying. These were their answers: $75, $2, $5, $0, $5. Why is the median more informative than the mean? The median is higher than the mean. O The mean is skewed by the outlier $75. O The mean is higher than the median. O The mean is skewed by the outlier $0.
For each problem, you must state the hypotheses, calculate the test statistic, and explain your decision. The following table reports the relationship between class standing and political orientation for a random sample of 267 college students. a. The table is constructed assuming that class standing is the independent variable. Please add %s in the appropriate position (columns or rows) to describe the pattern of the relationship. b. Is there a statistically significant relationship between these variables?
A class of students took a test. The instructor said that the 75th percentile score was 90 out of 100. What does this mean? A. 90% of the students scored 75 or more on the test. B. 75% of the students scored 90 or more on the test. C. 25% of the students scored 90 or more on the test. D. The high score in the class was (.75)(90).
A student earned grades of 74, 75, 79, and 91 on her four regular tests. She earned a grade of 75 on the final exam and 84 on her class projects. Her combined homework grade was 86. The four regular tests count for 40% of the final grade, the final exam counts for 30%, the project counts for 10%, and homework counts for 20%. What is her weighted mean grade? 80.0 80.6 80.5 81.1
