Answer: The critical value for a two-tailed t-test = 2.056
The critical value for a one-tailed t-test = 1.706
Step-by-step explanation:
Given : Degree of freedom : df= 26
Significance level : 
Using student's t distribution table , the critical value for a two-tailed t-test will be :-

The critical value for a two-tailed t-test = 2.056
Again, Using student's t distribution table , the critical value for a one-tailed t-test will be :-

The critical value for a one-tailed t-test = 1.706
Answer:
12.3 feet.
Step-by-step explanation:
As we are given that
is an right angled triangle.

And we have to find out the value of side OP to the nearest tenth of a foot by rounding off the value as seen in the attached figure as well.
By using Trigonometric functions in a right angled
, we know that:

Here,
is
, Perpendicular is side <em>OP</em> and Base is side <em>PN</em>.
So, 

Putting the values of <em>PN </em>and
.

Hence, the value of <em>OP </em>is
.
