 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the statements is false?
 A The t-distribution is bell-shaped and is shorter and wider than the standard normal curve. B The t-distribution is normally distributed. C The t-distribution is centered 0. D The calculation for the degree of freedom is df = n-1.
Explanation:

Detailed explanation-1: -The t-distribution is a type of normal distribution that is used for smaller sample sizes. Normally-distributed data form a bell shape when plotted on a graph, with more observations near the mean and fewer observations in the tails.

Detailed explanation-2: -What is the difference between the t-distribution and the standard normal distribution? The t-distribution gives more probability to observations in the tails of the distribution than the standard normal distribution (a.k.a. the z-distribution).

Detailed explanation-3: -Answer and Explanation: The t distribution is symmetrical, bell-shaped and its shape depends on the degrees of freedom. The mean of the t-distribution is 0. Hence, option (B) is correct.

Detailed explanation-4: -Answer and Explanation: The correct option is the last one: d. It is bimodal.
