Answer:
(c) The t-distribution is bell shaped
(e) The t-distribution has more values at the extremes than a standard normal distribution
(f) The t-distribution is centered at 0
Step-by-step explanation:
When the sample size is small or population variance is unknown, and we have to estimate population parameter then t- probability distribution is used.
The t-distribution has properties as follows:
- The mean of t-distribution is 0. Thus, option (f) is correct.
- t-distribution is normal. Thus, option (c) is correct.
- As compare to standard normal distribution, t-distribution has more values at the extremes. Thus, option (e) is correct.
