Recall that margin of error is given by:

Given that <span>you want to be 95% confident that the sample percentage is within 2.5 percentage points of the true population percentage.
This means that

and M = 2.5% = 0.025.
Part A:
When nothing is known about the percentage of persengers who prefer aisle seat, we make use of p = 50% = 0.5.
Thus,

Therefore, 1,537 </span><span>randomly selected air passengers must be surveyed to </span><span>be 95% confident that the sample percentage is within 2.5 percentage points of the true population percentage.
Part B:
Given that recent surveys surgest that about 38% of all air passengers</span> prefer an aisle seat, thus p = 38% = 0.38
<span>Thus,

Therefore, 1,449 </span>randomly selected air passengers must be surveyed to <span>be 95% confident that the sample percentage is within 2.5 percentage points of the true population percentage.</span>
Total unrealized holding gain would Beresford report in its 2021 income statement relative to its investments in bonds is $36,600.
Unrealized holding gains are increases in the value of assets that a company or individual continues to hold.
This gain has not yet been reported on the entity's income statement as a realized gain.
The gain is considered realized once the asset is sold.
Assets are frequently held even after a gain in value has occurred, either because the owner expects another gain or because the owner does not want to pay taxes on the gain.
Therefore, total unrealized holding gain is the difference between the fair value of trading securities on 12/31/2021 and at 12/31/2020.
For the figures used refer to the attached image.
total unrealized holding gain = (76000 - 65000) + (98100 - 67000) + (58500 - 64000)
= 11000 + 31100 - 5500
= $36,600
Hence, the correct answer is $36,600.

Answer:
The earnings per share figure is $1.89
Explanation:
Sales of $602,000
Costs of $256,000
Depreciation expense of $62,500
Interest expense of $29,500
Tax rate of 40 percent.
-> Profit Before Tax = Sales - Cost - Depreciation Expense - Interest expense
= $602,000 - $256,000 - $62,500 - $29,500
= $254,000
Net profit = Profit before Tax x (1 - Tax rate) = $254,000 * (1 - 40%) = $152,400
Earnings per share = (net profit - dividend paid for preferred stock)/ common stock outstanding = ($152,400-$44,500)/ 57,000
= $1.89
