The post-lunch dip is the drop in mental alertness after a midday meal. Does an extract of the leaves of the ginkgo tree reduce the post-lunch dip? Assign healthy people aged 18 to 40 years to take either ginkgo extract or a placebo pill. After lunch, ask them to read seven pages of random letters and place an X over every e. Count the number of misses per line read. M. K. Pawlik, "The effect of ginkgo biloba on the post-lunch dip and chemosensory function," MS thesis, Purdue University, 2002. What is a placebo and why was one group given a placebo? A placebo is a treatment pill that is presented to the individuals as a control treatment. A placebo is a lower-strength version of the pill that allows researchers to account for any physiological effect of taking the pill. O A placebo is an inert pill that allows researchers to account for any psychological effect of taking the pill. A placebo is a different pill that allows researchers to account for any variational effect of taking the…

The data found below measure the amounts of greenhouse gas emissions from three types of vehicles. The measurements are in tons per year, expressed as CO2 equivalents. Use a 0.025 significance level to test the claim that the different types of vehicle have the same mean amount of greenhouse gas emissions. Based on the results, does the type of vehicle appear to affect the amount of greenhouse gas emissions? A. Determine the test statistic. F= (Round to two decimal places as needed.) B. Identify the P-value. P-value= (Round to two decimal places as needed.)
