Question
In the figure below, the dotted vertical line indicates the upper 2.5% tail of the null distribution, while the solid vertical line indicates the lower 2.5% tail of the alternate distribution. The density of the null is shown in a dashed line, while the density of the alternate is shown in a solid line. Both the null and the alternate are normal distributions with equal variances. Imagine that instead of wanting to decrease false positives, you wanted to increase power, or decrease type II error. For example, you want to determine whether or not to send larvae found in still water in back yards to an entomologist to check for the mosquito vector of Zika virus. You don't want to miss any larvae that could grow to become a vector and spread the disease. How could you reduce this type of error with data behaving the way they do in the plot? probability density In -5 0 0.00 0.05 0.10 0.15 0.20 test statistic 5 10 Decrease alpha from 5% to 1% or lower Switch to a one-sided lower-tail hypothesis test Increase alpha from 5% to 10% or higher O Increase the cumulative probability of the alternate from 0.95 to 0.99 Decrease the cumulative probability of the alternate from 0.95 to 0.90
