Complete the energy range values for the 3rd orbital (2nd excited state) of Hydrogen. The electron can be placed in the 3rd orbital by manually dragging the electron or firing an Lβ photon once when the electron is in the ground state. Note also that the electron will deexcite with time and so it may need to be placed in the 2nd orbital repeatedly. 1st Excited State Electron in HRange 1 Range 2 Range30 to 1.9 ev(anything less that thisenergy will fall to excite the atom)

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
