Case 446

Standard Deviation???????????????

1)The average temperature in an american state was recorded as 98.7 F with a standard deviation of 0.7 F. If this is a normal model what percentage of the towns in this state were below 97 F?

Is this question simply a case of taking the Z-Score as 1.7 and reading off the table which I believe gives the answer of 0.446?

2) Species A of an animal weighs average of 50 pounds and has standard deviation of 3.3.

Species B average is 57.5 with standard deviation of 1.7.

A zoo has a species A weighing 45 pounds and B at 54 pounds. Explaining fully determine which is more underweight.

Could someone please direct me as to how i would go about finding this answer please.

You gota lurve elementary statistics questions where the question setter does not really understand statistics well enough to set questions that make any sense. Suppose the correlation scale for temperature is comparable to the size of a state?

I'm not insisting that the beginning student of statistics understand such subtleties, but I do insist that text book authors do.
