a. Distinguish between description and inference as reasons for using statistics. b. Suppose you have data for a population, such as obtained in a census. Explain why descriptive statistics are helpful, but inferential statistics are not needed. a. Which statement below best distinguishes description from inference? A. Statistical inference provides useful summaries of the data, while description helps make predictions and decide whether observed patterns are meaningful. B. Statistical inference provides useful summaries of data for a sample, while description...

Statistical inference brings to the scientific method an ability to know the probability of being correct (or incorrect) in reaching uncertain conclusions. A. In confidence interval estimation, the probability of being correct is the confidence level, 1 – alpha. B. In hypothesis testing, the probability of making a Type I error is the significance level, alpha C. The first statement above is true. D. Both statements above are true.
Which of the following statements about statistics and parameters is true?
Which of the following statements about statistics and parameters is true? Statistics are more reliable than parameters. Statistics are typically knowable, whereas parameters are typically unknown Parameters are easier to measure than statistics. Parameters are typically knowable, whereas statistics are typically unknown

Q2. The underlying principle of all statistical inference is one that uses sample statistics to learn something (that is to infer) about population parameter. Convince me that you understand this statement by writing a short paragraph describing an example in which you might use a sample estimate to infer about a population parameter. Clearly identify and define the terms: population, parameter, sample, sample-estimate and sample error in your example. Be as specific as possible. You may make up numbers. [8...
