Answer:
The value of your portfolio on May 3 is $16,058.
Explanation:
Since it is assumed that there is no tax, the value of a share on ex-dividend date is the current share per share minus the announced dividend per share share. Therefore, we have:
Price per share on ex-dividend date = Current share per share - Announced dividend per share share = $55 - $3.20 = $51.80
Therefore, the value of your portfolio on May 3 which is the ex-dividend date can be calculated as follows:
Portfolio value on May 3 = Number of shares owned * Price per share on ex-dividend date = 310 * $51.80 = $16,058
Therefore, the value of your portfolio on May 3 is $16,058.
Answer:
$10
Explanation:
Price Q Demanded Q Supplied Domestically Q Supplied by Importers $6 13,000 2,000 8,000
$7 12,000 4,000 8,000
$8 11,000 6,000 8,000
$9 10,000 8,000 8,000
<u>$10 9,000 = 9,000 </u><u> </u> 8,000
$11 8,000 10,000 8,000
If there is no international trade allowed, then we should look for the price at which the quantity demanded is equal to the quantity supplied by domestic producers. At $10 per widget, the total quantity demanded is 9,000 units and the total quantity supplied by domestic producers is 9,000 units.
Answer:
The mean withdraw has increased during weekend.
Explanation:
Assume that the withdraw amounts are normal distributed. To test whether the mean withdrawal has increased during weekends, we take a z-test. The z-test is possible because the observed sample (weekend transactions) is greater than 30.
The null hypothesis (
) is when the mean withdrawal is greater than 550. The alternative hypothesis (
) is when the mean withdrawal is equal to 550 or smaller. At an alpha of 0.05% is selected with a two-tailed test, , there is 0.025% of the samples in each tail, and the alpha has a critical value of 1.96 or -1.96. If the z-value is greater than 1.96 or less than -1.96, the null hypothesis is rejected.
z-value = (600-550) / 70 / 36^(1/2) = 0.1190
At α=0.05, the z-value < 1.96 and > -1.96, the null hypothesis is not rejected. Therefore, the mean withdraw has increased during weekend.
