The continuity correction.

Question

A television network claims that its current affairs program regularly attracts 34% of the total viewing audience. If 400 people, who were watching television at this time, were randomly surveyed, what is the probability that 150 or more people were watching the current affairs program on this network?  Hint: Use the continuity correction. 

Answer 1

You would be using the normal approximation to the binomial.

 

That being the case what would you use for the mean and standard deviation?
