Answer:
Step-by-step explanation:
Given function is
Domain of the function: (-∞,-3)∪(-3,∞) x | x ≠ -3
Holes: none. No common factors in numerator and denominator
VA: x = -3 as denominator is (x+3)
HA: No horizontal asymptote because degree of the denominator is less than numerator
OA: Roots are x = 3, -1 [(x-3) and (x+1) are the factors]
Y-Intercept: (0, -1) (by putting x = 0 in the given function)

The confidence interval for population mean is given by :-
(1)
, where = sample mean
z* = critical value.
SE = standard error
and ,
= population standard deviation.
n= sample size.
As per given , we have
n= 15
It is known that ring diameter is normally distributed.
By z-table ,
The critical value for 95% confidence = z*= 1.96
A 99% two-sided confidence interval on the true mean piston diameter :
(using (1))
[Rounded to three decimal places]
∴ A 99% two-sided confidence interval on the true mean piston diameter = (74.020, 74.022)
By z-table ,
The critical value for 95% confidence = z*= 1.96
A 95% lower confidence bound on the true mean piston diameter:
(using (1))
[Rounded to three decimal places]
∴ A 95% lower confidence bound on the true mean piston diameter= 74.020
