WebWhat causes type 1 errors? Type 1 errors can result from two sources: random chance and improper research techniques. Random chance: no random sample, whether it’s a pre-election poll or an A/B test, can ever perfectly represent the population it intends to describe.Since researchers sample a small portion of the total population, it’s possible … WebThat would then make P (type II error) = 0. This would make the power greater so b was, therefore, my choice. I now realize that my thinking was flawed because Ho is p=0.3, and it's false in all the options. The fact that p = 32% in b does not make Ho more true than in the other options (where the true p is farther from Ho). dabbs pawn shop southaven mississippi
