The automation of the workplace, which replaces workers with technology, is another cause of the changes in the job market.
<h3><u>
What is automation?</u></h3>
- A broad range of technologies that minimize human involvement in operations are referred to as automating.
- By predetermining decision criteria, subprocess linkages, and related actions — and embodying those predeterminations in computers – human intervention is decreased.
- An industrial control system with tens of thousands of input measurements and output control signals can be automated, as can a thermostat controlling a boiler in a home.
- The banking industry has also been impacted by automation. Control complexity can range from straightforward on-off control to sophisticated multivariable algorithms.
Automation is the use of a variety of tools and control systems, such as machinery, factory processes, boilers, and heat-treating ovens, as well as the activation of telephone networks and the steering and stabilization of ships, aircraft, and other applications and vehicles with a minimum of human intervention.

50,000×5=250,000
250,000÷4=625,000
250,000-625.000=375.00
Sum=375.00
The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
Answer:
c. News has no effect on stock prices.
Explanation:
A foreign exchange market can be defined as a type of market where the currency of a country is converted to that of another country. For example, the conversion of the United States of America dollars into naira, rands, yen, pounds, euros, etc., at the foreign exchange market.
Efficient market school is the market school which argues that forward exchange rates do the best possible job for forecasting future spot exchange rates, so investing in exchange rate forecasting services would be a waste of time because it is impossible to have a consistent alpha generation on a risk adjusted excess returns basis as market prices are only affected by new informations.
The efficient market school also known as the efficient market hypothesis (EMH) is a hypothesis which states that, asset (share) prices reflect all information and it is very much impossible to consistently beat the market. Also, forward exchange rates are exchange rates controlling foreign exchange transactions at a specific future date or time.
According to the efficient market hypothesis, News has an effect on
the prices at which a stock is sold because it affects demand and supply.
