The usual margin of error we strive for is a 95% probability that our estimate is within the margin. Assuming a normal distribution (and that we have a big enough sample not to worry about t tests) that corresponds to between minus and plus two standard deviations of the mean (remember the 68-95-99.7 rule). So our margin of error is plus or minus two standard deviations.

Answer: ±2%

Find the area. please

sashaice [31]

Answer:

16 cm²

Step-by-step explanation:

The figure is a trapezoid with two parallel sides.

The formula for the area is

A = ½(a + b)h

Data:

a = 5 cm

b = 3 cm

h = 4 cm

Calculation:

A = ½(5 + 3) × 4 = ½ × 8 × 4 = 16 cm²

The area of the trapezoid is 16 cm².
