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%

94/3 = 31.333

Step-by-step explanation:

The total hours worked = the amount of employees * hours worked

First I converted the mixed fraction 6 into

Then I multiplied it by the amount of employees.

* 5 =

= 31.33333
