Why does the significance level differ among industries? Will the null hypothesis be more likely to be rejected at ? = 0.01 than ? = 0.10? As the significance level increases to ? = 0.10 from ? = 0.01, which type error is more likely to occur? What can be done to reduce the likelihood of incurring this error?
