and 68.4 percentile for English. 4. Suppose you administered an anxiety test to a large sample of people and obtained normally distributed scores with a mean of 45 and standard deviation of 4. Do not use web-calculator to answer the following questions. Instead‚ you need to use the Z distribution table in Appendix A in Jackson’s book. A. If Andrew scored 45 on this test. What is his Z score? Andrew’s Z score would be zero. B. If Anna scored 30 on this test. What is her Z score?

Descriptive statistics is the discipline of quantitatively describing the main features of a collection of data.[1] Descriptive statistics are distinguished from inferential statistics (or inductive statistics)‚ in that descriptive statistics aim to summarize a sample‚ rather than use the data to learn about the population that the sample of data is thought to represent. This generally means that descriptive statistics‚ unlike inferential statistics‚ are not developed on the basis of probability
