The Power Of 10 Is Any Whole-Value (Integer) Exponent Of The Number 10. A Power Of 10 Is Any Number 10 Multiplied By Itself By The Number Indicated By Exponents. Shown In A Longer Form, A Power Of 10 Is The Number 1 Followed By "N" Zeros, Where "N" Is The Exponent And Is Greater Than Zero; Example

10 To The 6th Is Written As Shown

1,000,000

Now When "N" Is Less Than Zero THAT IS A TOTALLY DIFFERENT BALL GAME RIGHT THERE !

I believe it is 10 and however many zeros there are and there's 6 so if I'm not mistaken the answer is $10^{6}$ .

In an examination of purchasing patterns of shoppers, a sample of 16 shoppers revealed that they spent, on average, $54 per hour

Lesechka [4]

Answer:

$54-1.64\frac{21}{\sqrt{16}}=45.39$

$54 +1.64\frac{21}{\sqrt{16}}=62.61$

So on this case the 90% confidence interval would be given by (45.39;62.61)

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X=54$ represent the sample mean

$\mu$ population mean (variable of interest)

$\sigma=21$ represent the sample standard deviation

n=16 represent the sample size

Solution to the problem

The confidence interval for the mean is given by the following formula:

$\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (1)

Since the Confidence is 0.90 or 90%, the value of $\alpha=1-0.9=0.1$ and $\alpha/2 =0.05$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.05,0,1)".And we see that $z_{\alpha/2}=1.64$
