When establishing the confidence interval for the average weight of a cereal box, assume that the population standard deviation is known to be 2 ounces. based on a sample, the average weight of a sample of 20 boxes is 16 ounces. the appropriate test statistic to use is

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
