On August 1, 2022, Blue Spruce Corp. issued $507,600, 6%, 10-year bonds at face value. Interest is payable annually on August 1. Blue Spruce’s year-end is December 31. Prepare a tabular summary to record the following events. (a) The issuance of the bonds. (b) The accrual of interest on December 31, 2022. (c) The payment of interest on August 1, 2023. Include margin explanations for the changes in revenues and expenses. (If a transaction causes a decrease in Assets, Liabilities or Stockholders' Equity, place a negative sign (or parentheses) in front of the amount entered for the particular Asset, Liability or Equity item that was reduced.)

one set of data has more variation than the other. hope this !

x = 12

y = 1

for the points!

step-by-step explanation:

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
