Question

Calculate the deviation by subtracting the expected number from the observed number and record the calculation in the Deviation column for 20 coin tosses. The results are as follows: 10 heads and 10 tails.

A) Deviation = 0 for all 20 tosses.
B) Deviation = 1 for all 20 tosses.
C) Deviation = -1 for all 20 tosses.
D) Deviation = 0.5 for heads, -0.5 for tails.
E) Deviation = -0.5 for heads, 0.5 for tails.

Answer 1

The deviation for each coin toss in this scenario is 0. Therefore the correct answer is A) Deviation = 0 for all 20 tosses.

Step-by-step explanation:

The deviation is calculated by subtracting the expected number from the observed number.

In this case, we observed 10 heads and 10 tails out of 20 coin tosses.

To calculate the deviation for each toss:

Deviation = Observed number - Expected number.

Since the expected number of heads and tails is 10, the deviations for each toss would be:

A) Deviation = 0 for all 20 tosses.

This is because 10 - 10 equals 0 for every toss.
