Answer:

Step-by-step explanation:

From 8, we want to choose 4. So:

₈C₄ = 8! / (4! (8-4)!)

₈C₄ = 8! / (4! 4!)

₈C₄ = (8×7×6×5×4×3×2×1) / (4×3×2×1 × 4×3×2×1)

₈C₄ = (8×7×6×5) / (4×3×2×1)

₈C₄ = 70

There are 70 different teams you can form.

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
