GPAS of 13 randomly selected college students are given: 2.3 3.5 2.6 1.8 3.1 4.0 0.9 2.3 2.0 3.1 3.4 1.3 3.9 HINT: For #8 & #9, review graphing calculator steps for entering data and 1-Var Stats to have the mean and standard deviation calculated for nou, 8. Find the sample mean. 9. Find the sample standard deviation. Round to 2 decimal places. 10. Construct a 99% t-confidence interval for the population mean. 11. Interpret the confidence interval in a complete sentence. 12. You wish to estimate, with 99% confidence, the population proportion of U.S. adults who support labeling legislation for genetically modified organisms (GMOS). You estimate must be accurate within 3% of the population proportion. No preliminary estimate is available. Find the minimum sample size needed.
