Answer:
Step-by-step explanation:
A consumer electronics company is comparing the brightness of two different types of picture tubes for use in its television set
s. 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 iden- tical to that for type A. A random sample of n = 25 tubes of each type is selected, and XB - Xis computed. If us equals or exceeds ua, the manufacturer would like to adopt type B for use. The observed difference is XB - XA = 3.5. What decis would you make, and why?

<span> : This fraction is in the simplest form. It is equivalent to 0.2
The fraction is formed by dividing one part over five
</span>
<span> : This fraction is not in the simplest form. We can divide 5 by 5 and the answer would be 1. Therefore, </span><span> is equivalent to 1

<span> : This fraction is not in the simplest form. We can divide 5 by 1 and the answer would be 5. Therefore, </span><span> is equivalent to 5.
Based on the above, we can cnfirm that 0.2 , 1 and 5 are not equivalent.
Therefore, the given fractions are not equivalent
