Answer:
A. n = 22
Step-by-step explanation:
Hello!
The researcher conducted a one-sample t-tas with the following hypotheses:
H₀: μ = μ₀
H₁: μ ≠ μ₀
α:0.05
The one-sample t-test has "n-1" degrees of freedom and since the hypotheses are two-tailed you know that the rejection region will be divided into two tails with "α/2" for each tail. ±
If α:0.05 then α/2:0.025 and 1-α/2= 0.975
Using the given sample sizes as a reference you look in the table for the corresponding DF for an accumulated probability of 0.975
For n = 22
For n= 21
For n= 20
The correct answer is a) n= 22
I hope this helps!
The statement that correctly compares the angle measures m∠ABD = m∠ABE. The correct option is A. m∠ABD = m∠ABE
<h3>Measure of angles</h3>From the question, we are to determine the statement that correctly compares the angle measures
From the information,
Point E is added to the given figure so that point E <u>lies on segment BD</u> and it is <u>exactly halfway</u> between points B and D
From this, we can infer that
m∠ABD = m∠ABE
and
m∠DBC = m∠EBC
This is because, point E lies on segment BD and it does not affect the angle measures
Hence, the statement that correctly compares the angle measures m∠ABD = m∠ABE. The correct option is A. m∠ABD = m∠ABE
