Answer: 554
Step-by-step explanation:
If prior population proportion is known, then the formula to find the sample size is given by :-

As per given description, we have
p= 0.1
E=0.025
Critical z-value for 95% confidence : 
Then,

Hence, the minimum sample size required = 554.
Divide by -2: 3x-5 < -17
Add 5: 3x < -12
Divide by 3: x < -4 (answer)
Answer:
The statement
is neither a tautology nor a contradiction.
Step-by-step explanation:
A tautology is a statement that is always true.
A contradiction is a statement that is always false.
We are going to use a truth table to determine whether the statement
is a tautology, contradiction, or neither
A truth table shows how the truth or falsity of a compound statement depends on the truth or falsity of the simple statements from which it's constructed.
The statement
is compound by these simple statements:
and we are going to use these simple statements to build the truth table.
The last column contains true and false values. Therefore, the statement is neither a tautology nor a contradiction.
