You conduct a one-way ANOVA with 12 groups (or populations). At 0.05 significance level, you find at least one population (or group) mean is different (or statistically significant). Next,you are interested in finding which population (or group) means are different.   how many multiple two sample t tests could be conducted for this problem?  (Provide a whole number)     what is the adjusted significance level for those multiple two sample t test?  (Provide a value between 0 and 1 rounded to 3 decimal places)
