The standard deviation for a set of data is 6.5. The mean is 255. What is the Margin of Error?

HACTEHA [7]

Answer: The margin of error is 12.74.

Step-by-step explanation:

Since we have given that

Standard deviation = 6.5

Mean = 255

Let 95% level of significance,

So, z value = 1.96

We need to find the "Margin of error":

So, it becomes :

Margin of error = Standard deviation × z-value

Margin of error = $6.5\times 1.96=12.74$

Hence, the margin of error is 12.74.

Consider the following rational numbers -5.1 -5 1/3 -5 -5 3/5 list them in order from least to greatest

jok3333 [9.3K]

Answer:

-5.6, -5.3, -5.1, -5.

Step-by-step explanation:

Convert the first fraction to a decimal.

-5 1/3 is equal to -5.3333333333

Round to the nearest tenth.

-5.3333333333 rounded to the nearest tenth is -5.3.

-5 1/3 = -5.3.

Convert the second fraction to a decimal.

-5 3/5 is equal to -5.6.

The fraction is already rounded, so that's all for the second one.

-5 3/5 = -5.6.

The new set of numbers we have include -5.1, -5.3, -5, and -5.6.

We can now sort from least to greatest.

The first number is -5.6.

The second number is -5.3.

The third number is -5.1.

The fourth number is -5.

Listing the numbers -5.1, -5.3, -5, and -5.6 from least to greatest would result in -5.6, -5.3, -5.1, and finally -5.
