In a particular city, the population proportion π supports an increase in the minimum wage. for a random sample of size 2, let y = number who support an increase. a. assuming π = 0.50, specify the probabilities for the possible values y for y and find the distribution’s mean and standard deviation. b. suppose you observe y = 1 and do not know π . find and sketch the likelihood function. using the plotted likelihood function, explain why the ml estimate ˆ= π
