Answer:
tallest man height is more extreme.
Step-by-step explanation:
Given:
Heights of men at that time had a mean of 173.73 cm and a standard deviation of 8.65 cm.
Concept used:
Convert height into z scores for comparison of deviation from the mean.
Solution:
Tallest man height = 265 cm
Shortest man height = 109.1 cm
Thus we find that tallest man is 10.55 std deviations from the mean to the right and shortest man is 7.47 std deviations from the mean to the left.
Hence tallest man height is more extreme.

Answer:
The correct option is (d)-He wrote commutative instead of associative in Step 2.
Step-by-step explanation:
Commutative property:
Associative property:
Now consider the provided expression.
(6.2 − 1.6) − 4.4 + 7.8
Step 1
(6.2 − 1.6) − 4.4 + 7.8
Step 2 Use Associative property
6.2 + (−1.6 − 4.4) + 7.8
Step 3: Simplify
6.2 − 6 + 7.8
Step 4: Use commutative property
14 − 6
Step 5: Simplify
14 − 6 = 8
Hence, the wrong step is step 2. He wrote commutative instead of associative in Step 2.
Therefore, the correct option is (d)-He wrote commutative instead of associative in Step 2.
