Several students were tested for reaction times​ (in thousandths of a​ second) using their right and left hands.​ (Each value is the elapsed time between the release of a strip of paper and the instant that it is caught by the​ subject.) Results from five of the students are included in the graph to the right. Use a 0.02 significance level to test the claim that there is no difference between the reaction times of the right and left hands.  Right hand: 134  106  152  168  181  Left hand:     121  162  165  186  196

You read a newspaper article that says that 74% of households in your town participate in a recycling program.  To test that statement at the 10% significance level, you randomly select 54 households in town and you find that 35 of them participate in the recycling program. Ho: P=0.74                  Ha:P=/ 0.74 Find the P-value.  Round your answer to 3 decimal places.

n a 2014 study, Michael Smith arranged to be stung by bees repeatedly on 25 locations over 38 days to record the relative pain experienced by each sting in each body area.  A scale pain ratings of 1-10 were used with stings to the forearm defined to be a 5. What is the population of this study?
