Answer:
From the given data, the typical appropriation is utilized rather than t distribution for testing. The thicknesses of the curve similarly influence both normal distribution and territory of t distribution. The normal distribution test and t test give a similar dismissal for the invalid theory for any tail of the test. Besides, the tests normal sampling distribution and t sampling distribution give a similar dismissal to null hypothesis.
Along these lines, the outcomes got by utilizing normal distribution and t distribution are distinguished as same and for each situation, the tail thickness doesn't influence the event of the basic qualities.
Firstly we need to count what is the difference between both altitudes:
44,000 - 9,000 = 35,000
If a plane descends at a rate of 2,500 feet per minute, then we have to count how many 2,500s fit in 35,000:
35,000 / 2,500 = 14
It means that the jet will reach its cruising altitude in 14 minutes.
