Madhur L.
A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean breaking strength of 12 kilograms with a standard deviation of 0.5 kilograms. A sample of four specimens were collected from a batch of material the mean breaking strength was determined to be 11.5 kilograms. Perform an appropriate test to determine if the mean breaking strength is less than 12 kilograms. Use 5% significance.

'6_ For a random sample of 50 measurements On the breaking strength of cotton threads, the mean breaking strength was found to be 210 grams and the standard deviation 18 grams. Obtain confidence interval for the true mcan breaking strength of cotton threads of this type with confidence coefficient 0.95_'
