Q98: Predicting the characteristics of an entire group, after having measured a small group, is the major goal of inferential statistics.

Q99: Degrees of freedom for a single sample z-test is/are ‘n-1’.

Q100: Degrees of freedom for a single sample t-test is/are ‘n-1

Answer 1

Q97: The single-most critical component of deciding whether you are to conduct a t-test versus a z-test for hypothesis testing is whether there is a population mean.

True

Q98: Predicting the characteristics of an entire group, after having measured a small group, is the major goal of inferential statistics.

True

Q99: Degrees of freedom for a single sample z-test is/are ‘n-1’.

False

degree of freedom (n-1)not used in Z test for large sample where sample size n > 30

Q100: Degrees of freedom for a single sample t-test is/are ‘n-1

True

Degree of freedom (n-1) used in t test for small sample

sample is small where n is less than or equal to 30
