1. With a single-sample t ratio, the null hypothesis states that:

a) The sample mean could readily be part of the same distribution whose overall mean is already known.

b) the sample mean in all likelihood could not be part of the same distribution whose overall mean is already known

c) the sample mean and the population mean are significantly different values

d) none of these, since the null hypothesis always assumes that at least two sample means have been obtained

2. A single-sample t ratio is only considered to be significant when

a) the population values are known

b) the population values are assumed

c) its value falls within the confidence interval

d) the null hypothesis has been rejected
