A researcher wants to know if art majors have better visual memory than students in general. We obtain a mean visual memory test score of 50 in a sample of 25 art majors. We know that students in
general score a mean of 45 with a standard deviation of 14 on the same test. Use alpha of .05 and
the 6 steps of hypothesis testing to test this. For full credit, you must number and provide all six
steps of hypothesis testing. Make sure that you clearly describe your interpretation of the results in
step 6.

explanation:

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
