The null hypothesis should state that the proportion of viewers who watch the local CBS station's 11:00 PM newscast is equal to the percentage of the viewing audience claimed by the station based on Nielsen ratings, which is 41%. The correct null hypothesis is therefore "p = 0.41". Option B is the only choice that states this correctly.
