The average number of prisoners per state in the US between 2007 and 2016 is 424 with a standard deviation of 60. The total number of prisoners per year in Ohio, Missouri, and Oregon are presented in Table 1. Your goal is to find if the average number of prisoners in the US between 2008 and 2016 is different than the average number of prisoners in the state of the following question.

Table 1. Average number of prisoners per 100,000 people

What is the most likely p-value for your calculated test statistic? You do not need R for this answer. Input the letter you believe is correct.

1. >.05
2. <.05
3. Cannot be determined

4. What is your interpretation of your results? Input the letter here:

1. With 95% confidence we fail to reject the null that the sample mean number of prisoners per 100,000 in Oregon per year is equal to the mean number of prisoners per 100,000 per year in the US
2. With 95% confidence we reject the null that the sample mean number of prisoners per 100,000 in Oregon per year is equal to the mean number of prisoners per 100,000 per year in the US
3. With 95% confidence we accept the null that the sample mean number of prisoners per 100,000 in Oregon per year is equal to the mean number of prisoners per 100,000 per year in the US
4. We cannot make an interpretation.
