Explanation / Answer

Please Rate 5 Star for Help and Explaination

here we must find Confidence interval: 99.5%

data values:

0.00385 0.00358 0.00372 0.00418 0.00380 0.00399 0.00424 0.00375 0.00449 0.00422 0.00407 0.00434 0.00381 0.00421 0.00397 0.00425 0.00449 0.00462 0.00467 0.00404 0.00391 0.00431 0.00398 0.00415;

Ok now mean of data = 0.00404

variance = 0.00027

so Interval of production

CI= (
