When calculating the degrees of freedom for a hypothesis test comparing two population means with population variances that are unknown and assumed to be unequal, always round up the degrees of freedom to the next highest integer.
This makes it more challenging to reject the null hypothesis which is a more conservative approach. Indicate whether the statement is true or false
Q. 2The degrees of freedom for the appropriate critical value with a hypothesis test comparing two population means with population variances that are unknown but assumed to be equal are determined by .
Indicate whether the statement is true or false
Q. 3For a one-tail (lower) hypothesis test, if the z- or t-test statistic exceeds the critical value, we do not reject the null hypothesis.
Indicate whether the statement is true or false
Q. 4For a one-tail (upper) hypothesis test, if the z- or t-test statistic exceeds the critical value, we do not reject the null hypothesis.
Indicate whether the statement is true or false
