Answer:
The diagram is attached below.
Step-by-step explanation:
A normal distribution mean 0 and standard deviation 1 is known as the standard normal distribution.
So, the readings on the thermometers (denoted by <em>Z</em>) follows N (0, 1).
It is provided that 2.7% of the thermometers are rejected because they have readings that are too high and 2.7% are rejected because they have readings that are too low.
This implies that:
The value of <em>z</em> associated to both these probabilities are:
<em>z</em> = 1.93.
That is,
*Use a <em>z</em>-table.
The diagram for the two readings that are cutoff values separating the rejected thermometers from the others is attached below.
For this case we have the following linear function:
What we must do is equal the function to zero or equivalently, substitute the value of y = 0 in the given function.
We have then:
From here, we clear the value of x.
We have then:
Answer:
all real zeros of the function y = 2x-4 are:
x = 2
