When a chip fabrication facility is operating normally, the lifetime of a microchip operated at temperature measured in degrees celsius, is given by an exponential random variable with expected value =1/=(400/ years. occasionally, the chip fabrication plant has contamination problems and the chips tend to fail much more rapidly. to test for contamination problems, each day chips are subjected to a one-day test at =100∘c. based on the number of chips that fail in one day, design a significance test for the null hypothesis : the plant is operating normally. (a) suppose the rejection set of the test is ={> 0}. find the significance level of the test as a function of the number of chips tested.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
