I think the correct answer would be primary source. It is an account of an event created by someone who took part in or witnessed the event. It is also known as original source. It is any document, manuscript, diary, autobiography, artifact, recording or any source that was made at the time being studied. Examples are interviews, archives, photographs, letters, films and scrapbooks. When the data from these primary sources are obtained from other source wherein they are being analyzed and interpreted then these sources will be called as a secondary source. Examples are articles, books, magazines, surveys, internet resources.
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.
Answer:
A) change in the cost of eating index = <u>20% increase</u>
B) Suppose that consumers are completely indifferent between two chickens and one ham. For this example, how large is the substitution bias in the official "cost-of-eating" index?
The <u>INCREASE</u> in the cost-of-eating index is <u>18</u> %.
The <u>OVERESTIMATE</u> of inflation in the cost of eating reflects substitution bias.
Explanation:
2015
product units unit cost total
chickens 30 $4 $120
hams 10 $5 $50
<u>steaks 10 $8 $80</u>
total $250
2016
product units unit cost total
chickens 30 $5 $150
hams 10 $7 $70
<u>steaks 10 $8 $80</u>
total $300
A) ($300 - $250) / $250 = 20%
B)
if consumers are indifferent for 2 chickens per 1 ham, then the new basket should be assuming consumers will purchase the cheapest option:
2016
product units unit cost total
hams 25 $7 $175
<u>steaks 10 $8 $80</u>
total $255
the increase in inflation would have been = ($255 - $250) / $250 = 2%
the substitution bias = reported inflation - real inflation = 20% - 2% = 18%
