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

ans.

in united states (us), the first leading cause of death for both women and men is heart diseases that leads to more than half of the deaths. heart diseases develop due to narrow arteries, buildup of plaque in blood capillaries that arises difficulties in blood flow.

the second leading cause of deaths in us is cancer that affects individuals of all ages. it develops due to uncontrolled growth and spread of tumor cells, which results in death if the not controlled or treated.

the third leading cause of deaths in us is copd or chronic obstructive pulmonary disease. it includes difficulty in breathing, chest infections, and persistent cough. smocking is a leading cause of copd and around 80% of copd deaths occur due to smoking.

thus, the correct answer is 'option). cancer, copd, and heart disease.'
