4.25x10 to the power of 3 in standard notation
Leviafan [203]

The basic idea is that multiplying by 10 just moves the decimal point one place to the right.  It makes the number bigger.

Examples:

3.1 x 10 = 31

3.1 x 10 x 10 = 31 x 10 = 310

Each time you multiply by another 10, the decimal point moves one more place.

In your exercise, 10^3 says you're going to multiply by 10 <u>three</u> times in a row.  So that will move the decimal point 3 places to the right.

So what do you get if you move the decimal in 4.25 three places to the right?

Answer:

Descriptive Statistics

1) Descriptive Statistics

Descriptive statistics provide simple summaries about the sample and the measures. When using descriptive statistics you are simply describing what the data shows.

2) Inferential Statistics

On the other hand, inferential statistics try to reach conclusions that extend beyond the immediate data alone.

In this case the decision made was based on the "90% of the taste testers preferred", and no more than that.
