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. find a 95% two-sided confidence interval on the true mean breaking strength. round the answers to 1 decimal place.

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. =

i'm not sure what you mean but in todays world there is a lot of women that are the bread winners in the family. there is a lot more single mothers now that are going back to get an education which is boosting the economy. i believe there has been a boost in the economy due to women the cosmetic industry is boosting, chemist, the sky is becoming the limit for women in todays economy. most women are also putting off having kids just to make sure they have a education. i don't know how these two relate though to scriptures because it's not the way the lord wanted it. the man is suppose to be the bread winner and due to social media and the easy access we have there is a lot of cheating going on.
