Question

Assume that the readings on the thermometers are normally distributed with a mean of

0°
and standard deviation of
1.00°C.
Assume
2.9​%
of the thermometers are rejected because they have readings that are too high and another
2.9​%
are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others.

Answer 1

So far The 2.5% extreme, we have to find the supposed to this area. It should be 2.5% of .0025. We have to find P 2.5 or mhm 97.25. This extreme, so for this boat, the extreme from that table, that value will be -1.96, And this value is 1.96. This is the right from that table, and this is the required answer.
