HELP A.S.A.P!!!! The data to represent average test scores for a class of 16 students includes an outlier value of 78. If the ou

kolezko [41]

When the outlier is removed The mean would increase.

<u>Step-by-step explanation:</u>

Outliers are the value that lies outside the set of data. i.e. the data doesn't fit in the group.

Removing outliers can affect mean more than median. Because outlier removal sometimes affect the median but in a small percentage or sometimes it will remain the same.

Let us prove, consider 16 values one with 78 and other 15 with values nearly 85, 84 that will give the mean value as 84.

78, 84, 82, 86, 84, 85, 83, 86, 82, 85, 84, 83, 86, 85, 86, 85.

Mean = $\frac{Sum of the values}{Number of values}$ .

Mean = $\frac{78+84+82+86+84+85+83+86+82+85+84+83+86+85+86+85}{16}$ .

Mean = $\frac{1344}{16}$ .

Mean = 84.

Remove 78 from the data set then the data set is 84, 82, 86, 84, 85, 83, 86, 82, 85, 84, 83, 86, 85, 86, 85 and number of data is reduced to 15.

Mean = $\frac{84+82+86+84+85+83+86+82+85+84+83+86+85+86+85}{15}$ .

Mean = $\frac{1266}{15}$ .

Mean = 84.4.

The mean is increased.

Math please help :)!!!

Answer:

36, 8.5

Step-by-step explanation:

an exponent of two means that you are multiply a number by itself

so in this case you would multiply 6 by itself: 6 x 6

this gets you 36

and 8.5 doesn't change so its just 8.5

Bernardo is converting a fraction, StartFraction a Over b EndFraction, to a percent. Both a and b are whole numbers and not equa

anyanavicka [17]

Answer:

$Percent = \frac{100a}{b}\%$

Step-by-step explanation:

Given

$\frac{a}{b}$

Required

Convert to fraction

To do this, we simply multiply the fraction by 100%

This gives:

$Percent = \frac{a}{b} * 100\%$

$Percent = \frac{a * 100}{b}\%$

$Percent = \frac{100a}{b}\%$

The expression cannot be further simplified.

Take for instance the fraction is: $\frac{2}{5}$

Using the same analysis, the percentage would be:

$Percent = \frac{2}{5} * 100\%$

$Percent = \frac{2 * 100}{5}\%$

$Percent = \frac{200}{5}\%$

$Percent = 40\%$
