Human body temperatures have a mean of 98.20 degrees fahrenheit and a standard deviation of 0.62 degrees fahrenheit. convert 103.00 degrees fahrenheit to a z-score and determine if it is usual of unusual. unusual means that the z-score is more than 2 standard deviations below or above the mean.

z-score will be:  7.741....  and it will be unusual.

Step-by-step explanation:

Human body temperatures have a mean of 98.20 degrees Fahrenheit and a standard deviation of 0.62 degrees Fahrenheit.

So here,   and

Formula for z-score is:  

Thus, the z-score for 103.00 degrees Fahrenheit will be.......

As, here the z-score is more than 2 standard deviations above the mean, so 103.00 degrees Fahrenheit is unusual for human body temperature.

450 is the final answer! : )

all but the second one

step-by-step explanation:

cuz that one goes over 180
