Dr. Victory is a child psychologist with an inner-city school district. He wants to estimate the proportion of middle school students who have felt bullied.LUSE SALT(a) What is the minimum number of students that will need to be observed to get a margin of error of 0.08 with 90% confidence? (Use a table or technology.)students(b) Dr. Victory's school superintendent, Dr. Triumph, finds out about the study and tells him that in past studies, approximately 60% of middle school students have felt bullied.Will having this knowledge change how many students will be needed for Dr. Victory's students? Yes or no?YesO NoMY NOTES PRACTICE ANOTHE(c) Now that Dr. Triumph has told Dr. Victory that in previous studies approximately 60% of students have felt bullied, what is the minimum number of students that will need to be observed to get a margin of error of 0.08 with 90% confidence?

The Bureau of Labor Statistics reports that the official unemployment rate for Black people was 10.4% and 4.7% for White people in February 2015. Select all correct answers for this question. O The samples of white and black people are independent. The explanatory variable is the unemployment rate. The response variable is the unemployment rate. The response variable is race.
One study found a negative correlation between participant’s age and hours of sleep they got (as they got older, they slept less). Which additional fact would lead you to believe that the relationship between age and hours of sleep is one of causation and not correlation? Jim is 63 and sleeps more than he did when he 47. Josie is 40 and sleeps fewer hours than when she was 30. The participants were randomly selected, the sample size was large, and the participants did not know the goal of the study. Jennie sometimes has difficulty sleeping.
A researcher gathered a sample of participants who volunteered for a studying of phobias. She measured anxiety level of participants as they viewed photos of spiders and again when they viewed puppies. Which statistical test is appropriate for this study and why?
Twenty years ago, 56% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 247 of 700 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the a = 0.01 level of significance. 5% of the population size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis Because npo (1-Po) = 172.5 > 10, the sample size is less than are satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? 0.56 versus H,: p # 0.56 Ho: (Type integers or decimals. Do not round.) %D Find the test statistic. Zo = (Round to two decimal places as needed.) %D
Lynn University wants to examine whether students display better academic performance in class versus online. They have collected GPAs of two different samples of students, a sample from classes that take place in-person and a sample from classes that take place online. The data set is below. They predict that in-class students perform better than online students. GPA's In Class GPA Online GPA 4.0 4.0 3.5 2.2 3.7 3.3 3.5 3.7 2.0 2.5 3.2 3.8 3.3 3.8 What type of t-test should we use for this research question? Group of answer choices a) One sample b) Independent samples c) Paired Samples
The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 52 records of automobile driver fatalities in a certain county showed that 35 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County? Use ? = 0.10. What is the value of the sample test statistic? (Round your answer to two decimal places.)=__ (c)Find the P-value of the test statistic. (Round your answer to four decimal places.)=__

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
Should an observational study or an experiment be performed to answer the research question below? Explain your choice. Do students who miss their classes frequently earn lower grades than those who attend a high percentage of their classes?
Customers of a restaurant have been complaining about food poisoning over the past week. A health professional was called to investigate. He tested a representative sample of the eggs and reported that 23% of the sample eggs tested positive for the salmonella bacterium. If a second health professional tests 4 eggs at random, what is the mean of the number of eggs that test positive for salmonella?
