Answer – C. the sample size 16 is too small

 

If we toss a coin 16 times in order to test the hypothesis H0: p = 0.5 that the coin is balanced, we can't use the z-test for a proportion in the situations because the sample size 16 is too small. The z-test is best used when the sample size is greater than 30; when the sample size is less than 30, t-test is more appropriate.

The measure of Angle E, the angle of elevation from point A to point B, is left-parenthesis 3 x plus 1 right parenthesis-degrees
Anuta_ua [19.1K]

Answer:

∠D = ∠E = 46°  

Step-by-step explanation:

∠D and ∠E are interior opposite angles.

      ∠D = ∠E

2(x + 8) = 3x + 1

2x + 16 = 3x + 1

          x = 15°

∠D = 2(15 + 8) = 2 × 23 = 46°

∠E = 3× 15+ 1 = 45 + 1  = 46°
