When resources are low, businesses know that they can increase their prices because people need them desperately.
Given:
n = 4000, sample size
p = 16% = 0.16, the proportionof theose who watch60 minnures.
Confidence interval (CI) = 95%
The z* parameter is 1.96 for 95% CI, so the confidence interval is
That is
0.16 +/- 1.96*√[(0.16*0.81)/4000]
= 0.16 +/- 0.114
= (0.1486, 0.1714)
Answer:
The 95% confidence interval is approximately (15%, 17%) or 15% ≤ p ≤ 17%.
Note:
To correct for the fact that we are using a discrete distribution to match a continuous distribution, it is customary to subtract 0.5/n from the lower limit and to add it to the upper limit.
If this correction is applied, the 95% confidence interval becomes
(0.1486-0.5/4000, 0.1714+0.5/4000)
= (0.1485, 0.1715)
or
15% ≤ p ≤ 17%
The correction does not affect the result in a significant way.
Answer:
b. independent variable
Explanation:
The “treatment” in an experiment is also the independent variable, which is the variable that is controlled or manipulated to bring about a change or effect on the dependent variable.It is the variable the in which, when the value is manipulated or changed, it influences the value of the dependent variable. For example, income as an independent variable, when manipulated in an experiment can influence a dependent variable such as household consumption. Changes to the independent variable result in changes in the dependent variable.
Answer:
"Pivoting" is an idea that is exceptionally well known in fire up associations. The corporate group utilizes the expression called, on the off chance that you have faced a challenge and you understand you're falling flat, bomb quicker and go for plan B. Here, turning is viewed as an instrument that assists with finding things that the association may have over looked. Associations need to go further their unique objectives and goals, think like their clients and take care of issues.
Let us consider a case of an organization called Earth Networks. It started as a homeroom science gear association in 1990s, interfacing understudies with climate estimate data.
- Due to innovation and the web, it made a huge difference. Earth Networks the executives acknowledged it was turning into a quickly developing media company that could sell publicizing close by ongoing meteorological forecasts gave by a developing number of associated climate stations.
- Eight thousand associated climate stations later, their 'Climate bug" application currently has the most complete neighborhood climate data accessible.
- Meteorologists and well-being authorities in nearby and national government organizations—and speculative stock investments, as well—utilize the application to get them a level of detail they never envisioned.
- The re imagination of Earth Networks as a system sensor and information examination organization was only the primary significant advance one which opened new markets and income streams.
- A second re-imagination practice opened one more new market - utilizing system detecting and information investigation to assemble point by point data on the source and stream of ozone harming substances, around the world.
- That is called rotating for development.
Answer:
$47,500
Explanation:
The computation of the dollars amount for meeting the obligation is shown below:
= Expected amount to pay × forward rate
= 5,000,000 × $0.0095
= $47,500
We simply multiply the Expected amount to pay with the forward rate so that the accurate amount can come.
All other information which is given is not relevant. Hence, ignored it
