Consider the t distribution with 21 degrees of freedom. a. What proportion of the area under the curve lies to the left of t = -2.518?

1%

Step-by-step explanation:

Given that :

Degree of freedom (df) = 21

What proportion of the area under the curve lies to the left of t = -2.518?

Using the online t value calculator :

P(t ≤ - 2.518) = 0.01

Hence, proportion of area under the curve which lies to the left of - 2.518 with degree of freedom (df = 21) is 0.01 = 1%

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

the answer is the third / last answer
