If a majority of the residents in the community oppose the coal terminal (success), the mayor will also oppose it; otherwise the mayor will support it.

The explanation is different for categorical and quantitative data. We will begin with categorical data.

The director wrote her back saying “women are not physiologically able to run marathon distances, and we wouldn't want to take the medical liability. “6 That was during a time when opportunities were limited for women because of the assumption they were physically incapable of doing many of the things that men could do.

Recall that the binomial distribution shows the probability of the possible number of successes in a sample of size n when there were only two possible independent outcomes, success and failure. What happens if there are more than two possible outcomes however?

However, there are times when the researchers do not have a hypothesis. In such cases they would simply like a good estimate of the parameter.

If there are three tables, with the head table being number 1, then after each round of play, winning players move up one table with the goal of being at the head table (the one closest to the food!).
