II. Science Majors

In a graduate teacher college, a survey was conducted to determine the proportion of students who want to major in Science. If 308 out of 850 students said YES, with 95% confidence, what interpretation can you make regarding the probability that all students in the teacher education graduate college want to major in Science?

Note: Follow the Four-Step process in estimating the population proportion.

III. Food Combo

In a certain food stall, 278 out of 500 randomly selected consumers indicate their preference for a new kind of food combination. Use a 99% confidence interval to estimate the true proportion ρ who like the new food combination. What course of actions could concerned individuals like entrepreneurs take based on the results of your estimates?
