A consumer electronics company is comparing the brightness of two different types of picture tubes for use in its television sets. Tube type A has mean brightness of 100 and standard deviation of 16, and tube type B has unknown mean brightness, but the standard deviation is assumed to be identical to that for type A. A random sample of n = 25 tubes of each type is selected, and Xpar B – Xbar A is computed. If ug equals or exceeds uA, the manufacturer would like to adopt type B for use. The observed difference is barB Ibar A 3.5. What decision would you make, and why?

Question
A consumer electronics company is comparing the brightness of two
different types of picture tubes for use in its television sets. Tube type A
has mean brightness of 100 and standard deviation of 16, and tube type
B has unknown mean brightness, but the standard deviation is assumed
to be identical to that for type A. A random sample of n = 25 tubes of
each type is selected, and Xpar B – XbarA is computed. If ug equals or
exceeds uA, the manufacturer would like to adopt type B for use. The
observed difference is xhar B - Ibar A = 3.5. What decision would you
make, and why?
