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...

QUESTION 10 What is the difference between a parameter and a statistic? O Parameters are sample values and statistics are population values. O None of the above. O Parameters are population values and statistics are sample values. O Parameters and statistics are both sample values. There is no difference between them. O Parameters and statistics are both population values. There is no difference between them. QUESTION 11 What is the sampling distribution of a statistic? O The distribution of statistic...

Question 8 1 pts Suppose we calculate sample means from two populations. While the sample means are not identical, the difference between them seems to be small. How can a statistical test help here? It can determine whether the population means are different It can determine whether the population means are identical It can determine whether the difference is statistically reasonable if the population means are different It can determine whether the difference is statistically reasonable if the population means...
