Answer:
Step-by-step explanation:
Given:
1/2(ln(xx + yy) − ln(zz))
Now,
From the properties of log function,
1) n × ln(x) = ln(xⁿ)
and,
2) ln(A) - ln(B) =
applying the properties in the given equation
we get the above equation as:
( using the property 2 we get (ln(xx + yy) − ln(zz) =
or
⇒ ( using the property 1 i.e n × ln(x) = ln(xⁿ) )
expression as an equivalent expression with a single logarithm is
Answer : There are no more than 10% of homes in the city are not up to the current electric codes but actually we do not have evidence to accept it.
Explanation:
The Type I error occurs when the null hypothesis is true but we reject it.
Given null hypothesis : : an electrician claims that no more than 10% of homes in the city are not up to the current electric codes.
The Type I error for the given situation is that there are no more than 10% of homes in the city are not up to the current electric codes but actually we do not have evidence to accept it.
