Acompany produces precision 1000‑millimeter rulers. the actual distribution of the lengths of the rulers produced by this company is normal, with mean and standard deviation =0.02 millimeters. suppose i select a simple random sample of four of the rulers produced by the company and i measure their lengths in millimeters. the sample yields ¯=1000 . a 90% confidence interval for is:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

how to award brainliest:

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.
