Body temperatures of healthy humans are distributed nearly normally with mean 98.2of and standard deviation 0.73of. what is the cutoff for the highest 10% of human body temperatures?

oF is the cutoff for the highest 10% of human body temperatures

Explanation:

The confidence interval for this problem is %

We will first evaluate the z-value for 90% confidence interval considering it one tailed.

Z from the statics table is equal to

Formula for z - value

where

x represents the required cut off value

u represents the mean value

and α represents the standard deviation

Substituting the values in above equation, we get -

Hence,

oF is the cutoff for the highest 10% of human body temperatures

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
