Answer:
6^5 * 9^5
Step-by-step explanation:
( 6*9) ^5
We know that ( ab) ^c = a^ c* b^c
6^5 * 9^5
Using confidence interval concepts, it is found that:
a) The point estimate is the sample mean.
b) The confidence interval is: ![\overline{x} \pm T\frac{s}{n}](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%20%5Cpm%20T%5Cfrac%7Bs%7D%7Bn%7D)
c) If $1411 is between the bounds of the interval yes, otherwise no.
--------------
- At item a, it asks to provide a point estimate for the population mean, which is the sample mean
![\overline{x}](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D)
--------------
Item b:
- In the spreadsheet, it is possible to find the <em>standard deviation for the sample</em>, thus, the t-distribution is used.
- The confidence interval will be given by:
![\overline{x} \pm T\frac{s}{n}](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%20%5Cpm%20T%5Cfrac%7Bs%7D%7Bn%7D)
In which:
is the sample mean.- T is the critical value, from the t-distribution, with a two-tailed area of
and n-1 degrees of freedom. - s is the standard deviation for the sample.
- n is the sample size.
--------------
Item c:
We have to check if 1411 is between
and
.
- If it is, the interval includes the National Average, otherwise, it does not.

Answer:
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present.
Step-by-step explanation:

Original Number
------------------------------------
3000
------------------------------------
Increase
------------------------------------
5.4% of 3000
= 0.054 x 3000
= 162
------------------------------------
New Total
------------------------------------
3000 + 162 = 3162
------------------------------------
Answer: 3162
