President Trump passed an executive bill, banning Chinese airplanes from landing in America, and Chinese Post Graduate students from studying in America. As Chinese tourists and students contribute greatly to the US economy, how do you think this law by President trump will affect US productivity and economic growth? Comment particularly on human capital, physical capital, technology, natural resources, and labour

Dr. Song has spent all her life studying education outcomes and policy in the US. Recently, an article claimed that 6.6% of U. S. students take advanced placement exams. Dr. Song’s work with a random sample of 1,200 students shows that this number is actually 7.5%. Set up Dr. Song’s hypotheses and provide the appropriate test. What do you conclude?

According to national data, about 15% of American college students earn a graduate degree. Using this estimate, what is the probability that exactly 27 undergraduates in a random sample of 200 students will earn a college degree? Hint: Use the normal approximation to the binomial distribution, where p = 0.15 and q = 0.85. (Round your answer to four decimal places.) Incorrect: Your answer is incorrect.

A random sample of the ACT scores of 300 students at Big State University provided a sample mean score of 21.8 with a sample standard deviation of 5.632. Find the 95% confidence interval for the mean score of all Big State students who had taken the ACT.?
(a) (21.2, 22.4) (b) (21.0, 22.6) (c) (20.9, 22.7) (d) (20.3, 23.3) (e) (21.3, 22.3)

Full-time college students report spending a mean of 32 hours per week on academic activities, both inside and outside the classroom. Assume the standard deviation of time spent on academic activities is 6 hours.

If you select a random sample of 25 full-time college students, what is the probability that the mean time spent on academic activities is at least 30 hours per week?

Invitations to a party are sent to 100 student.

a) Suppose that for every student, the chance that he or she will attend the party is 40% if it rains and 80% if it does not rain. If the weather forecast says it will rain with a probability of 30%, how many students are expected to show up for the party?

b) Find the probability that at least 70 students show up for the party. If you use approximation methods, state and check the conditions.

Age of College Students Find the 80% confidence intervals for the variance and standard deviation of the ages of seniors at Oak Park College if a random sample of 23 students has a standard deviation of 2.9 years. Assume the variable is normally distributed. Use the chi-square distribution table to find any chi-square values to three decimal places. Round the final answers to one decimal place.
