The standard deviation for the sample of five perfumed hands was 12.052%. Conduct the 5 steps of hypothesis testing for the effect of the perfume against the control.
Biology researchers examined the mosquito-repelling effects of a control (no scent), insect repellents that contain DEET, natural insect repellents, and several beauty products (Rodriguez, Drake, Price, Hammond, & Hansen, 2015). In the control condition, on average, 61% of a swarm of mosquitoes chose to enter a chamber with a hand in it. For the purposes of this exercise, we’ll treat this as the population mean. When the hand was sprayed with a high concentration of Victoria’s Secret Bombshell perfume, only 17% of mosquitoes entered the chamber on average. The standard deviation for the sample of five perfumed hands was 12.052%. Conduct the 5 steps of hypothesis testing for the effect of the perfume against the control.
