Answer:
log(5/4)
Step-by-step explanation:
You have to apply the properties of logarithms to the given expression in order to obtain a form with a single logarithm.
For example, the quotient rule:
In this case, log(x) = log (5/6 ) and log(y)= log (2/3)
Therefore x = 5/6 and y = 2/3
Applying the rule:
log (5/6 )− log (2/3) =
Solving the argument of the logarithm (The division of the fractions)
The equivalent form is:
log(5/4)
Answer: (1583.63, 1672.37)
Step-by-step explanation:
Given : Sample size : n= 83
Sample mean :
Sample standard deviation :
The population standard deviation is unknown .
The confidence interval for population mean :
For 90% confidence , significance level =
Using t-distribution table , Critical t-value =
, where n-1 is the degree of freedom.
Now , 90% confidence interval for the mean square footage of all the homes in that city will be :-
Hence, the 90% confidence interval for the mean square footage of all the homes in that city = (1583.63, 1672.37)
