Are these TRUE or FALSE
If an unpaired 2-sample t-test produces a p-value <0.05, thenthe distribution of the variable in group 1 does not overlap at allwith the distribution of the variable in group 2.
If you plot the mean and SEM error bars for 2 different groups,and the error bars do not overlap between the 2 groups, then it'sguaranteed that the 2 groups have significantly different means(p<0.05).
If a 95% CI for a difference in 2 means (from a 2-sampleunpaired t-test) contains the null value of 0, then the p-value< 0.05 and we reject the null hypothesis at significance levelalpha=0.05.
