Hello,

$y=2^{x}$
==> $log_{2}(y) =x*log_{2}(2)$
==> $log_{2}(y) =x*1$
==> $x=log_{2}(y)$

Answer B

The correlation coefficient for poor hearing and loud music in a group of people is 0.67. Analyze the following statement: Poor

Montano1993 [528]

Answer:

Correlation does not mean <em>causation</em> even after having a relatively high correlation coefficient as a result.

Step-by-step explanation:

Correlation and causation are not the same. Correlation does not mean that variations in one variable <em>cause</em> variations in the second variable. Instead, correlation considers that variations in one variable <em>corresponds</em> with variations of the second variable. No more.

Correlation is an important first step to establish that one variable possibly can cause some effect on the other, but it is not a definitive answer to this question. It is crucial to find other possible factors that can explain what causes some effect.

As a conclusion, a positive and relative high correlation coefficient does not necessarily mean causation. It simply tells us that some study found that people that listen to loud music are also people with poor hearing problems, and possibly a cause to the latter variable is to listen loud music repeatedly, but it is a must to find other possible factors before definitely concluding that.

Determine the five-number summary for this data set, taking into account any outliers. 10 13 15 12 12 4 12 17 12 13 15 18 10 11

TiliK225 [7]

The value of the median, lower and upper quartile

Median = 21.5
lower quartile = 12
upper quartile = 29

<h3>What is the five-number summary for this data set?</h3>

The minimum value = 10

The maximum value = 38

The median is the value that is found in the center of the data when it is ordered from lowest to highest. In the event that there is no value that precisely corresponds to the center, the value will be determined by taking the average of the values that are located on each side of the middle.

10 11 12 15 19 24 27 29 33 38

Median = 21.5

The intermediate value of the data that is located to the left of the median is known as the lower quartile.

10 11 12 15 19

lower quartile = 12

The intermediate value of the data that is located to the right of the median is known as the upper quartile.

24 27 29 33 38

upper quartile = 29

In conclusion, the 5 number summary is 10, 12, 21.5, 29, 38 → A
