shtirl [24]

Answer:

Z=2.49 and this Z-score is “unusual.”

Step-by-step explanation:

To calculate the Z score use the following formula

Z=\frac{x-\mu}{\sigma}

Where

μ is the average

\sigma is the standard deviation

x is the data to which we will calculate the z-score

In this case

\mu = 122.3\\\\\sigma= 18.5\\\\x =168.4

So

Z=\frac{168.4-122.3}{18.5}

Z=2.49

A z-score is unusual if Z> 2 or Z < -2

Finally

Z=2.49 and this Z-score is “unusual.”
