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. =
