Step-by-step explanation:
Sample size (n) = 50
Sample mean weight (X) = 210 grams
Sample standard deviation (s) = 18 grams
Confidence coefficient (Z) at 90% = 1.645
The confidence interval for the true mean breaking strength of cotton threads of this type, at a 90% confidence level, is given by:

The confidence interval is 205.81 grams to 214.19 grams.
-4^4= -4*-4*-4*-4
-4*-4=16
16*-4=-64
-64*-4= 256
