Problem 1 a. Which of the measured values in the table below are equal to the expected ones within one-sigma confidence level? measured mean to Expected value value 15.432 0.025 0.050 15.489 1.23 10-3 1 10-5 2 x10-5 1.22 x10-3 ii 2.95 x 100 0.03x10° 0.06x10 2.85 x100 b. How would your answers in achange for the case of a two-sigma confidence level.

Explanation / Answer

a)only ii is at  equal to the expected ones within one-sigma confidence level becuase expected value - meaured mean value should be less than sigma which is only in ii

b)ii is within one sigma level and so it is also in 2 sigma level.

i is not in 2 sigma level as the differnce is greater than 2 sigma

iii is also not in 2 sigma lvl.
