This value is the probability of rejecting the null hypothesis when it is true. Correct decision or Type I Error This value is the probability of a "miss." alpha A "miss" can only occur when the reality in the population is this. reject null hypothesis A "false alarm" can only occur when the statistical outcome is this. null hypothesis is false If the null hypothesis is rejected, either of these outcomes may be true. beta Failing to reject a false null hypothesis increase Rejecting a true null hypothesis a “miss”

Unformatted text preview: The probability of making a type I error fail to reject null hypothesis Lowering the alpha from .05 to .01 has this effect on the likelihood of rejecting the null 1-B The value of power is equal to this. decrease Power is increased as this type of error is increased. Type I error Increasing alpha will have this effect on false alarms. Type II error Increasing power will decrease the likelihood of this. The statistical decision must be this if Type II error is a possibility alpha Type I error...
