The number of ways you can pick 3 people from 9 = 9*8*7 / 3*2*1 = 84

So chance of picking the 3 suspects = 1 / 84.

The number of ways to pick 3 from the 6 innocent people = 6*5*4 / 3*2*1 = 20

Chances of picking 3 innocent people = 20 / 84  or 5/21

sukhopar [10]

Answer: I and III

Step-by-step explanation:

We observe in the case provided that the researcher, who has no interest in the population to intervene, is going to carry out surveys to assess whether the neighborhood is a good place to live, obtaining the following conclusions:

i. The Minneapolis Resident Survey was an observational study.

ii. The Minneapolis Resident Survey was an experiment.

iii. The figure 50.1% is a descriptive statistic for the sample.

iv. The figure 50.1% is a statistical inference for the population.:By estimating the sample, obtained by a lower percentage of the total of the respondents, it is known that with a 95% confidence interval that the rating obtained from the respondents considering that the neighborhood is a good place to live was found between 0.44 and 0.50, taking this interval as a statistical inference for the population.

The correct answer is I and III, since in this study no interventions were made to the population and only one observation of a characteristic of the neighborhood was made and in III we know that the descriptive statistic only describes data and summarizes it, which is a of the ways to display the data from the descriptive survey.
