Higher values of \alpha α make it easier to reject the null hypothesis, so choosing higher values for \alpha α can reduce the probability of a Type II error. how to use odin to flash custom romSince in a real experiment it is impossible to avoid all type I and type II errors, it is important to consider the amount of risk one is willing to take to falsely reject H0 or accept H0. The solution to this question would be to report the p-value or significance level α of the statistic. For example, if the p-value of a test statistic result is estimated at 0.0596, then there is a probability of 5.96% that we falsely reject H0. Or, if we say, the statistic is performed at level α, like 0.05, then we allow to … how to use ocusoft eyelid scrub
