Chapter 5 Complete all steps for the following tests using StatKey or Table A. (Refer to "Steps for CI & HT" handout.) 1. Using the dataset Florida Lakes, is there evidence of a negative correlation between pH in lakes and mercury levels in fish? Assume the conditions for inference are met, and that the p-value is less than 0.005. There is no need to find the test-statistic since we already have a p-value, but comment on all other steps for this test. CHO 08020-01819 - MacBook Air #tv a) Does this provide evidence that more than 65% of US adults believe in ghosts? Include all steps (including checking conditions for Normality using the null proportion) and show your work on the calculations. An approximate standard error is SE = 0.01508. t b) Find and interpret a 95% confidence interval for the proportion of all US adults who do not believe in ghosts using the normal distribution. Include all steps (including checking conditions for normality using the sample data) and show your work on the calculations. An approximate standard error is SE = 0.01463. 7 G C #tv @ ? P Sho
