The linear function y = -0.3x + 26 models the percentage of men in a certain city, y, smoking cigarettes 3 years after 2000. Find the slope for the model. Then describe what this
means in terms of the rate of change of male smokers in this city over time.

Given a normal distribution with µ =50 and σ =4, what is the probability that 5% of the values are less than what x values? between what two x values (symmetrically distributed around the mean) are 95 % of the values? instructions: show all your work as to how you have reached your answer. don’t simply state the results. show graphs where necessary.
