A researcher is interested in knowing if there are differences between the incidence of accidents among (1) employees who received only video safety training and (2) employees who received hands-on safety training.
They were able to collect 102 responses from a random number of employees. Among them, 27 video-only employees were in accidents, 36 were not; 23 hands-on training were in accidents, 16 were not. Construct a contingency table. Run the Chi-Square test for independence using the calculator in the Module.
State your findings and their significance. Do not forget to give summary statistics in APA format.
A researcher has found that pilots taking an over the counter antihistamine have poor reaction times. They performed an experiment on 22 pilots: 11 took the medication and 11 did not. Their reaction times to a command by Air Traffic Control was considered to be adequate or inadequate. Among those taking the medication, 9 were rated inadequate and 2 adequate. Among those not taking the medication, 10 were rated adequate and only 1 inadequate. Construct a contingency table. Run the Chi-Square test for independence using the calculator in the module. Construct a contingency table.
