Answer :
Mean is 98.8
Standard Deviation is 0.6
Probability is 0.8790
What is the value?
Mean:
=AVERAGE(A1:A10)
=98.8
Standard Deviation:
=STDEV.S(A1:A10)
=0.6
Using the 68-95-99.7 Rule, we can assume a normal distribution. The probability of a body temperature less than 99.5 is the area to the left of 99.5 under the normal curve.
z-score:
=(99.5 - 98.8) / 0.6
=1.17
Using the standard normal distribution table (z-table), we find:
Probability:
=P(Z
≈0.8790
So, the probability of a body temperature less than 99.5 is approximately 0.8790.
