Since the value of the bond increases by 4% each year and only 1 year passed by then the ROI is not compounded and we only need to find the value before the 4% was implemented. In order to add 4% to a value we would multiply that value by 1.04 which increases that value by 4%. So, to find the value before the interest was added we would need to divide the new value by 1.04 instead.
$156 / 1.04 = $150
Finally, we can see that the value of the bond when Tyler's mom purchased it was 150
19. The mean of the sampling distribution is the same as the population mean, d. 18.6
20. The standard deviation of the sampling distribuion is the population standard deviation divided by the square root of the sample size. 6.0/√36 = 1.0
