Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and standard deviation of 1.00degreesc. assume 2.8% of the thermometers are rejected because they have readings that are too high and another 2.8% 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.

Using the normal distribution, it is found that the cutoff values are -1.91 ºC and 1.91 ºC.

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

In this problem:

The cutoff values are:

Then, for Z = -1.91.

And, the upper cutoff is:

The cutoff values are -1.91 ºC and 1.91 ºC.

The sketch of the situation is given at the end of this question, with the accepted values.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
