Answer:
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
s=5 represent the sample standard deviation
n=130 represent the sample size
For this case we can't set a margin of error just with a % since they not specify 1.13% respect to something for this case we can omit this value
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.99 or 99%, the significance would be 
and 
, and the critical value would be 
And replacing we got:
Answer:
range is 10
Step-by-step explanation:
highest number is 49
loweest number is 39
49 - 39 = 10
3 units + 1 unit = 4 units (the sum of 2nd and 3rd)
4 units + 4 units = 8 units (sum of all properties)
*The other 4 units comes from the first property as the first property's value is the same as the sum of the 2nd and 3rd.*
8 units = $560 000
1 unit = $560 000÷8 = $70 000 (3rd)
3 units = 3x$70 000= $210 000 (2nd)
$210 000 + $70 000=$280 000 (1st)
Ans:
1st property costs $280 000.
2nd property costs $210 000.
3rd property costs $70 000.
