The mean of these statistic is 2.18.

Step-by-step explanation:

According to the chart, from 1986-1996, unintentional drug overdose deaths per 100,000 population began to rise.

The given data set is

2, 1, 2, 2, 1, 2, 2, 3, 3, 3, 3

Formula for mean:

$Mean=\frac{\sum x}{n}$

Using this formula, the mean of the data is

$Mean=\frac{2+1+2+2+1+2+2+3+3+3+3}{11}$

$Mean=\frac{24}{11}$

Mean=2.181818

$Mean\approx 2.18$

Therefore the mean of these statistic is 2.18.

Answer from: GunnerWilbert5178

The mean of these statistics is $\large{\boxed{\bold{2.18}}$

Further explanation

Statistics is a study of a collection, preparation, analysis,presentation/conclusions from some data

Data is a collection of information presented in the form of numbers

Data collection can be done through a sample that represents all data (can be called a population) that is used as research

Data information can be stated in tables, diagrams or graphs

Tables are usually in the form of frequency tables that show the frequency distribution of dataDiagrams can be in the form of bar charts, pie charts, line charts or pictograms

The average value or mean is a measure to provide an overview of a set of data

Mean is the average of a number of data

To determine the mean: the sum of all data divided by the amount of data

General formula

$\large{\boxed{\bold{mean=\frac{\sum_{xi}}{n} }}}$

xi = data

n = amount of data

The numbers for each year for unintentional drug overdose deaths per 100,000 population are: 2, 1, 2, 2, 1, 2, 2, 3, 3, 3, 3

Total amount of data:

$\displaystyle 2+1+2+2+1+2+2+3+3+3+3=\large{\boxed{24}$

Amount of data: $\large{\boxed{11}}$

So the mean value:

$\displaystyle mean=\frac{\sum_{xi}}{n}=\frac{24}{11}=\large{\boxed{\bold{2.18}}}$

Answer from: Quest

a) one student is chosen from classroom a, then a student is chosen from classroom b.

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b. this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes. this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes. this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes. this makes them dependent events.
