The value given below is discrete. Use the continuity correction and describe the region of the normal distribution that corresp
onds to the indicated probability. Probability of fewer than 8 passengers who do not show up for a flight Choose the correct answer below. A. The area to the right of 8.5 B. The area between 7.5 and 8.5 C. The area to the right of 7.5 D. The area to the left of 7.5 E. The area to the left of 8.5
If fewer than 8 passengers do not show up for a flight, then at most 7 passengers do not show up for a flight. Therefore, applying continuity correction, the area under the curve must comprehend from zero to seven passengers not showing up, but not the 8th passenger. Thus, the area must be to the left of 7.5.
So basically you use the ratio they have given you. You either multiply by 2 if image is enlarged or divide by 2 if it is reduced. (Keep in mind I got the 2 from your ratio : 1inch : 2inches) Therefore the find the original width, you multiply 10 by 2, giving you 20 inches.
