Answer:
- A
- A
- C
- B
Step-by-step explanation:
1) The statement is true. A larger margin of error creates a wider confidence interval, which is more likely to contain the population parameter.
2) The statement is false. A larger sample size decreases the standard error of the sample proportion, which decreases the margin of error.
3) The statement is true. A smaller sample size increases the standard error of the sample proportion, which, for a fixed margin of error, decreases the critical value, z*.
4) The statement is true. One can see from the margin of error formula that the margin of error is inversely proportional to the square root of n.
-15×-5=75 I don't know of this helped but whatever
The answer is 2.35714285714!
hope this helps!!
Follow the formula Interest=(Principal)(Rate)(Time)
So, the equation would be:
I= 10,000x0.09x5
This equals $4,500
So, the amount of interest is $4,500
Answer:
Step-by-step explanation:
we know that
The algebraic expression of seven-tenths is equal to the number 7 divided by ten
The algebraic expression of the product of 5p and 3 is equal to multiply 5p by 3
therefore
The algebraic expression of seven-tenths of the product of 5p and 3 is equal to
