Two random samples are taken, one from among UVA students and the other from among UNC students. Both groups are asked if academics are their top priority. A summary of the sample sizes and proportions of each group answering yes'' are given below: UVA (Pop. 1):UNC (Pop. 2):n₁=81,n₂=85,p^{_^}1=0.8 p^2=0.663

Find a 96.3% confidence interval for the difference p₁−p₂ of the population proportions.

11. Research conducted a few years ago showed that 35% of Temple students had travelled outside the US (conventional wisdom). Temple has recently implemented a new study abroad program and results of a new survey show that out of the 100 randomly sampled students 42 have travelled abroad. Conduct a two-tailed hypothesis test against the conventional wisdom with α = .10. Then, confirm your answer by constructing a 90% confidence interval

A biology professor claims that, on the average, 10% of her students get a grade of A, 30% get a B, 40% get a C, 10% get a D, and 10% get an F. The grades of a random sample of 100 students were recorded. The following table presents the results. Grade A B C D F Observed 10 34 46 6 4 Test the hypothesis that the grades follow the distribution claimed by the professor. Use the α = 0.05 level of significance.

The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level.

Step 2 of 2 :  

Suppose a sample of 966 tenth graders is drawn. Of the students sampled, 802 read above the eighth grade level. Using the data, construct the 98% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level. Round your answers to three decimal places.

High school students across the nation compete in a financial capability challenge each year by taking a National Financial Capability Challenge Exam. Students who score in the top 18 percent are recognized publicly for their achievement by the Department of the Treasury. Assuming a normal distribution, how many standard deviations above the mean does a student have to score to be publicly recognized? (Round your answer to 2 decimal places.)

Case study: Electronic Healthcare System Issues

A group of nursing students are discussing client safety during a clinical experience. The clinical instructor mentions that the hospital is interested in addressing The Joint Commission’s patient safety goals that are associated with the use of health information technology.

1. Which Joint Commission safety goals are directly related to health information technology?
2. How can a group of nursing students impact the recommendations concerning alarm safety cited by the Joint Commission?

The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level.

Step 2 of 2: Suppose a sample of 1042 tenth graders is drawn. Of the students sampled, 865 read above the eighth grade level. Using the data, construct the 90% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level. Round your answers to three decimal places.

A researcher is interested in whether students randomly assigned to 1 of 3 sleep deprivation conditions (i.e., low, medium, or high sleep deprivation) perform the same, on average, on a math exam. Assume alpha = 0.05, and there are 10 students in each condition. (SS_total= 16,071       and      SS_within= 7,880)

Please sketch and complete the following table on scratch paper to help with Questions 25-34:

What is the SS_Total?

Some undergraduates think tertiary institutions should focus on online learning and find ways of inculcating this in the conventional institutions such that, even at the end of the Covid-19 pandemic, students can continue to learn online. But some students disagreed with the online learning option. Do you agree or disagree? Give reasons to support your opinion. Your argument should clearly identify the issue, provide credible reasons, and have a convincing conclusion.

The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level.

Step 2 of 2 :  

Suppose a sample of 333 tenth graders is drawn. Of the students sampled, 254 read above the eighth grade level. Using the data, construct the 80% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level. Round your answers to three decimal places.
