An ABC News poll asked adults whether they felt genetically modified food was safe to eat. Thirty-five percent felt it was safe, 52% felt it was not safe, and 13% had no opinion. A random sample of 120 adults was asked the same question at a local county fair. Forty people felt that genetically modified food was safe, 60 felt that it was not safe, and 20 had no opinion. At the 0.01 level of significance, is there sufficient evidence to conclude that the proportions differ from those reported in the poll

The conclusion for a test statistic is either to reject the null hypothesis" or to "not reject the null hypothesis". A good statistician NEVER "accepts the alternate hypothesis". Explain the reason you either "reject the null hypothesis" or "do not reject the null hypothesis". Explanation should be at least 5-7 sentences."

Answer:

Step-by-step explanation:

Hello!

The null hypothesis is the commonly accepted fact, if you were to make an experiment, you'll state in the null hypothesis what is already known of your population, another way to see it is that the null hypothesis has the "no change" statement. When doing a statistic test you seek to nullify the null hypothesis to replace it with the alternative hypothesis, i.e., the objective of any hypothesis test is to invalidate this hypothesis not to prove the alternative hypothesis right.

In short words, you work to annulate what is accepted knowledge and not to prove what you think happens.
