a. the t-distribution is dependent on the sample size.
b. the t-distribution does not depend on the sample size.
c. the t-distribution has more values at the extremes than a standard normal distribution.
d. the t-distribution has fewer values at the extremes than a standard normal distribution.
e. the t-distribution is bell-shaped and centered at its degrees of freedom.
f. the t-distribution is bell-shaped and centered at 0.
g. with larger samples, the t-distribution is closer to a normal distribution.
h. with smaller samples, the t-distribution is closer to a normal distribution.

a. The t-distribution is dependent on the sample size.

c. The t-distribution has more values at the extremes than a standard normal distribution.

f. The t-distribution is bell-shaped and centered at 0.

Explanation:

T-distribution is used in statistics and probability is a part of distribution and it looks similar to the normal distribution curve. T-distribution is also known as Student t-distribution.

a. The t-distribution is dependent on the sample size.

-- This statement is true.

   The t-distribution curve depends on the sample size. They are mostly used for smaller sample size.

c. The t-distribution has more values at the extremes than a standard normal distribution.

-- This statement is true.

   The t-distribution is similar to the normal distribution and is bell shaped and is symmetric, but it has heavier tails.

f. The t-distribution is bell-shaped and centered at 0.

-- This statement is true.

   The t-distribution is bell shaped an zero at center.

the most likely outcome of fewer loon territories is that hawks would increase in proportion because the benefit of victory would be greater. hawks and loons are natural rivals of resources and victories in the game, since the lakes drying up affected the loons, the hawks would be benefited from the drought.
