Answer:
For this case we have this function given:
In order to find the domain we need to find the possible values of x that the function can assume.
And we know that for this case the logarithm for 0 or neagtive numbers is not possible to calculate it, so then we can say that the domain for this case is:
And we can write this in formal notation as:
And the best answer for this case would be:
all real numbers greater than 0

Answer:
Step-by-step explanation:
Given : Past experience has indicated that the breaking strength of yarn used in manufacturing drapery material is normally distributed and that σ = 4 psi.
A random sample of 8 specimens is tested, and the average breaking strength is found to be 98 psi.
i.e. n= 8 and
Critical value for 95% confidence =
Confidence interval for population mean :-
i.e.
Hence, a 95% two-sided confidence interval on the true mean breaking strength. =
