Answer:
0.195
Step-by-step explanation:
Given:
For ; sample size, n = 9 ;
Standard Error (S. E) = 0.39
S. E = σ / sqrt(n)
σ = standard deviation
0.39 = σ / sqrt(9)
σ = 0.39 * 3
σ = 1.17
Therefore, For n = 36
S. E = 1.17 / sqrt(36)
S.E = 1.17 / 6
S.E = 0.195
The height of the plane when it gets to the tower would be 600 yards, which is greater than the height of the tower. Hence, <em>"the plane clears the tower with about 6 yards to spare." </em>
<u>Given</u><u> </u><u>the</u><u> </u><u>Parameters</u><u> </u><u>:</u>
- <em>Initial distance traveled = 1500</em>
- <em>Yards to control tower = 600</em>
- <em>Height of control tower = 198 feets = (198×3) = 594 yards </em>
If the rate of ascent of the airplane is proportional to the distance traveled, that is (1 yard length = 1 yard height gained).
Then after traveling 600 yards to the position of the control tower, then the height of the plane would be 600 yards
<u>Difference in height</u> :
- <em>Height of plane - Height of tower</em>
(600 yards - 594 yards) = 6 yards
Therefore, the most appropriate Statement is that, "<em>the</em><em> </em><em>plane</em><em> </em><em>clears</em><em> </em><em>the</em><em> </em><em>tower</em><em> </em><em>with</em><em> </em><em>about</em><em> </em><em>6</em><em> </em><em>yards</em><em> </em><em>to</em><em> </em><em>spare</em><em>.</em><em>"</em><em> </em>
