Stream TV? ~ A Pew research study claims that: "Those with a college education are more likely than those with less education to say their primary way to watch TV is online streaming." The poll results showed that 114 out of 341 college educated adults, and 81 out of 296 non-college educated adults said they mainly watch TV via streaming. We want to determine if the proportion of college educated adults, who primarily watch TV via online streaming is higher than the proportion of non-college educated adults. Notation: 1=college educated and 2=non-college educated. A normal distribution is used to carry out a hypothesis test for this scenario. What is the pooled estimate for the common value of the population proportion?
