It is claimed that an industrial safety program is effective in reducing the loss of working hours due to factory accidents. The data below show the weekly loss of working hours due to accidents in six plants both before and after the safety program is initiated. Does the data substantiate the claim that the safety program has reduced the loss of working hours? Use RStudio to perform a repeated-sample t-test with α = .05. Print your computed t-statistic, your crit- ical t-value, and explain your conclusion. PlantNum Before After 1 12 10 2 29 28 3 16 17 4 37 35 5 28 25 6 15 16
