Answer:

probably 4.5

"Step-by-step explanation:

To break even, we need the total profit to be equal to 0. If we make x dollars in 2012, then we need to solve

2.5 + 1.75 + (-3.3) + (-1.4) + x = 0

This gives us x = 0.45 in thousands.

Since the question asks us to give the answer in hundreds, we multiply by 10 and get 4.5. Thus the profit in 2012 must be 4.5 (in hundreds) to break even."

Several factors are involved in the creation of a confidence interval. Among them are the sample size, the level of confidence,
Lynna [10]

Answer:

  1. A
  2. A
  3. C
  4. 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.
