Construction of a con?dence interval

Reference no: EM13965430

1. (a) How does the t-distribution compare with the normal distribution?

(b) How does the difference affect the size of con?dence intervals constructed using z (normal approximation) relative to those constructed using the t-distribution?

(c) Does sample size make a difference?

(d) What assumptions do we need to make in using the t-distribution for the construction of a con?dence interval?
