Solve for number 8 only
![C. When the sample size is considered small.
D. When the sample size is sufficiently large.
7. In the estimation of a parameter using the t-distribution, is it possible to replace
the population standard deviation, o by the sample standard deviation, s?
A. No, because the given sample size is small
B. No, because o and s differ by a significant amount
C. Yes, because o is unknown and s is a good estimator of o.
D. Yes, because o is equal to s when we are estimating parameters
8. What will be the effect on the t distribution curve when we replace o by s?
A. The t-distribution curve will become bell-shaped.
B. The t-distribution curve will be symmetrical to zero.
C. The t-distribution curve will be the same as the normal curve.
D. The t-distribution curve will have a lower peak and thicker tails.
