Question

Mark is using a one-sample t-test on the following group:

Answer 1

Based on the one-sample t-test that Mark is using, the two true statements are:

• c.)The value for the degrees of freedom for Mark's sample population is five.
• d.)The t-distribution that Mark uses has thicker tails than a standard normal distribution.

What are the degrees of freedom?

The number of subjects in the data given by Mark is 6 subjects.

The degrees of freedom can be found as:

= n - 1

= 6 - 1

= 5

This is a low degrees of freedom and one characteristic of low degrees of freedom is that their tails are shorter and thicker when compared to standard normal distributions.

Options for this question are:

• a.)The t-distribution that Mark uses has thinner tails than a standard distribution.
• b.)Mark would use the population standard deviation to calculate a t-distribution.
• c.)The value for the degrees of freedom for Mark's sample population is five.
• d.)The t-distribution that Mark uses has thicker tails than a standard normal distribution.
• e.)The value for the degrees of freedom for Mark's sample population is six.
