tailieunhanh - Ebook Statistics (12th edition): Part 1

(BQ) Part 1 book "Statistics" has contents: Statistics, data, and statistical thinking; methods for describing sets of data; probability; discrete random variables; continuous random variables, sampling distributions; inferences based on a single sample - Estimation with confidence intervals; inferences based on a single sample - Tests of hypothesis. | Applet Concept Illustrated Description Applet Activity Standard deviation Investigates how distribution shape and spread affect standard deviation. Students visualize relationship between mean , 64; , 64; , 65; , 85 and standard deviation by adding and deleting data points; applet updates mean and standard deviation. Confidence intervals for a proportion Not all confidence intervals contain the population proportion. Investigates the meaning of 95% and 99% confidence. Simulates selecting 100 random samples from the population and finds the 95% and 99% confidence intervals for each. Students specify population proportion and sample size; applet plots confidence intervals and reports number and proportion containing true proportion. , 325; , 325 Confidence intervals for a mean (the impact of confidence level) Not all confidence intervals contain the population mean. Investigates the meaning of 95% and 99% confidence. Simulates selecting 100 random samples from population; finds 95% and 99% confidence intervals for each. Students specify sample size, distribution shape, and population mean and standard deviation; applet plots confidence intervals and reports number and proportion containing true mean. , 306; , 307 Confidence intervals for a mean (not knowing standard deviation) Confidence intervals obtained using the sample standard deviation are different from those obtained using the population standard deviation. Investigates effect of not knowing the population standard deviation. Simulates selecting 100 random samples from , 316; , 316 the population and finds the 95% z-interval and 95% t-interval for each. Students specify sample size, distribution shape, and population mean and standard deviation; applet plots confidence intervals and reports number and proportion containing true mean. Hypothesis tests for a proportion Not all tests of hypotheses lead correctly to either rejecting or failing to reject the .
