It has been found that the average time internet users spend online per week is 18.3 hours.
A random sample of 48 teenagers indicated that their mean amount of internet time per week was 20.9 hours with a population variance of 32.49. At the 0.02 level of significance, can it be concluded that the mean time differs from 18.3 hours per week?

0, elsewhere
Find
(i) the value of k.
(ii) the conditional expectation of Z given X= x,Y= y
Near the equator, the earth's magnetic field points almost horizontally to the north and has magnitude B = 0.5 x 10 ^-4 T. What should be the magnitude and direction for the velocity of an electron if its weight is exactly balanced by the magnetic pole?
