<span>Group A (distance in miles) 1 1.5 3.03 3.2 2.8 1.5 1.8 2.5 2.2
Group B (distance in miles) 2 2.5 3.23 1.3 1.8 2.4 3 1.5 1.8
Group A mean = (1 + 1.5 + 3.03 + 3.2 + 2.8 + 1.5 + 1.8 + 2.5 + 2.2)/9 = 19.53/9 = 2.17
Group B mean = (2 + 2.5 + 3.23 + 1.3 + 1.8 + 2.4 + 3 + 1.5 + 1.8)/9 = 19.53/9 = 2.17
Therefore, the mean is equal for Group A and Group B.

Hello it’s me I’ve been wondering if after all these years
You just multiply 1.5x10^3 by 4.3x10^2. 1.5x10^3 is equal to 1500 (move the decimal to the right as many spaces as the exponent gives) and 4.3x10^2 is equal to 430. 1500*430=645000. To get that back down to scientific notation, we would have to move the decimal back to between the 6 and 4 to get 6.45 (Zeros aren't included in scientific notation) We moved the decimal to the left five spaces do the exponent is 10^5. We are left with 6.45x10^5
The expected value for the person buying the insurance is -25.
<h3>How the expected value is calculated?</h3>
The expected value is the average gain or loss of an event if the event is repeated a number of times.
Expected value = ∑xP(x)
<h3>Calculation:</h3>
It is given that,
The probability of a 47-year-old woman passing away during the coming year is 0.179% = 0.00179
The death benefit = $100,000 - $204 = $99,796
The loss from living = -204
Then the expected value = 99796(0.00179) + (-204)(0.99821) = -25
Therefore, the expected value for the person buying the insurance is -25.
