The solution to the Question is given as
- df= 49
- t critical value = 2.01
- The number of degrees of freedom for a collection of sample data is the number of sample values that are determined after certain restrictions have been imposed on all data values.
<h3>What is the number of degrees of freedom that should be used for finding the critical value t a/2?</h3>
a)
Generally, the equation for degrees of freedom is mathematically given as
df= n-1
Therefore
df= 50-1
df= 49
b)
For the critical value
Confidence interval= 95%
df= 49
Solving using a critical value calculator we have
t critical value = 2.01
c)
In conclusion, The number of degrees of freedom for a collection of sample data is the number of sample values that are determined after certain restrictions have been imposed on all data values. Option D is correct

The answer would be -4h. hope this helps!
42,678 is greater than 42,067 because....(break it down)
42,000

8
volume = l x w x h
volume = 20 x 35 x 50 = 35,000 cubic cm
1 cubic cm = 0.001 liter
35000 x 0.001 = 35 liters of water is needed
Answer: 1.29
Step-by-step explanation: 0.5 is the equivalent to 0.50. Adding this to .74 gives us the sum of 1.29
