You are a researcher who wants to know what the mean (µ) level of anxiety would be for the whole population if they were all receiving a new anti-anxiety therapy. You can’t give the therapy to the whole population, so you give it to a sample, and you get M = 32.1 as the average anxiety level for the sample on the therapy. What is the reason that you can’t just simply assume that µ = 32.1? You didn’t use random assignment Sampling error Descriptive statistics Inferential statistics
You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ=61.7σ=61.7. You would like to be 95% confident that your esimate is within 2.5 of the true population mean. How large of a sample size is required?n = Do not round mid-calculation. However, use a critical value accurate to three decimal places — this is important for the system to be able to give hints for incorrect answers.

Consider the problem of diagnosing a rare disease. Let’s say the occurrence of thisdisease is one in a thousand i.e. P(D = +) = 0.001. There is a test T which correctlyidentifies the disease 99.9% of the time, i.e. P(T = +|D = +) = 0.999. However, italso has a false positive rate of 0.02, i.e. P(T = +|D = −) = 0.02 i. If a random person from the population is tested, what is the probability they willreceive a positive test, i.e. P(T = +)? ii. Given that the test is positive, what is the probability that the person has the disease,i.e. P(D = +|T = +)?

Ben thinks that people living in a rural environment have a healthierlifestyle than other people. He believes the average lifespan in the USA is 77years. A random sample of 12 obituaries from newspapers from rural towns inIdaho give x = 81.61 and s = 2.76. Does this sample provide evidence thatpeople living in rural Idaho communities live longer than 77 years?(a) State the null and alternative hypotheses: (Type "mu" for the symbol u , e.g.mu >1 for the mean is greater than 1, mu < 1 for the mean is less than 1, mu not= 1 for the mean is not equal to 1)H:H:(b) Find the test statistic, t =(c) Answer the question: Does this sample provide evidence that people living inrural Idaho communities live longer than 77 years?
