9 Question 2In an environmental impact study for a new airport, the noise levels of various jets werejust seconds after their wheels left the ground. The jets were either wide-bodied or narow-bodied. The noise levels (decibels) for 12 wide-bodied jets and 10 narrow-bodied jets wererecorded:wide109.5narrow131.4107.3105126.8114.1117.3126.9105.4113.7108.2122121.71069109.2108.1116.3115.5106.4111.6104.6110.5а)Descnbe the datab)Test if there is difference in the decibel levels of wide-bodied and narrow-bodiedjets?c)What is the confidence intervals in the decibel levels of wide-bodied and narrow-bodied jets?

There are two types of jets i.e., wide bodied and narrow bodied. Noise levels in decibels are…

In an environmental impact study for a new airport, the noise levels of various jets were just seconds after their wheels left the ground. The jets were either wide-bodied or narrow- bodied. The noise levels (decibels) for 12 wide-bodied jets and 10 narrow-bodied jets were recorded: wide 109.5 107.3 narrow 131.4 126.8 105 114.1 117.3 126.9 105.4 108.2 113.7 122 121.7 106.9 109.2 116.3 108.1 115.5 106.4 111.6 104.6 110.5 a) Descnibe the data Test if there is difference in the decibel levels of wide-bodied and narrow-bodied jets?
