Answer:

3^{-2} * 3^3

Step-by-step explanation:

vova2212 [387]

Answer:

The margin of error for the 99% confidence level for this sample is ±2.23.

None of the given figures is close to the answer:

E. None of the above

Step-by-step explanation:

margin of error (ME) around the mean can be calculated using the formula

ME=\frac{z*s}{\sqrt{N} } where

  • z is the corresponding statistic of the 99% confidence level (2.576)
  • s is the population IQ standard deviation (15)
  • N is the sample size (300)

Using these numbers we get:

ME=\frac{2.576*15}{\sqrt{300} }  ≈ 2.23
