The tallest living man at one time had a height of 230 cm. the shortest living man at that time had a height of 91.3 cm. heights of men at that time had a mean of 170.53 cm and a standard deviation of 5.91 cm. which of these two men had the height that was more extreme?

The shortest living man at that time had the height that was more extreme.

Step-by-step explanation:

We will z scores to solve this exercise. The formula we need is:

Where is the raw score, is the mean and is the standard deviation.

We know at that time heights of men had a mean of 170.53 centimeters and a standard deviation of 5.91 centimeters, then:

Knowing that the tallest living man at that time had a height of 230 centimeters, we get:

And knowing that the shortest living man at that time had a height of 91.3 centimeters, we get:

Based on this, we can conclude that the shortest living man at that time had the height that was more extreme.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
