Step 8This is a two-tailed test, so we are concerned about the critical values that give a total area of 0.05 in boththe upper and lower tails. Therefore, each tail will have an area equal to half of 0.05, or 0.025. Any teststatistic greater than or equal to the positive critical value or less than or equal to the negative critical valuewill result in the null hypothesis being rejected.
