The ability to generalize a study's results to different circumstances is known as external validity that suffers from 7 types of threats.
<h3>What are the threats to External Validity?</h3>
There are 7 major threats to external validity.
- The first threat is sampling bias, in which a sample is not representative of the population.
- The second threat is history, where an unrelated incident can affect the results.
- The third threat is observer bias, in which the traits or actions of the experimenter unintentionally affect the results, resulting in bias and other demand features.
- The fourth threat is the Hawthorne effect, which describes the propensity for individuals to alter their behaviour merely because they are aware that they are being observed.
- The fifth threat is the Testing Effect, in which the results are impacted by whether a test is administered before or after another.
- The sixth threat is the aptitude-treatment, which involves the interaction of individual and group factors to affect the dependent variable.
- The environment, time of day, location, researcher traits, and other variables that restrict the generalizability of the results are included in the seventh threat.

The time that Carlene would have to wait to buy the desk is 4 years.
<h3>How long would it take before Carlene can afford to buy the desk?</h3>
When an amount of money is compounded, it means that both the amount that was invested and the interest accrued earn interest.
The formula that can be used to determine the time is
N = log(FV / PV) / log(e) / interest rate
log(500 / 400) / log(e) / 0.06 = 3.71 years = 4 years

Seth is certainly the one who needs a long term care insurance.
A long term care insurance is a policy that covers the nursing bills for older citizens who are 65 years and above. It is an advance payment that covers about six or more years.
Such a policy is of more importance to Seth who has spent most of the money that he has made and keeps spending. He may not have enough money to cover his nursing bills in old age but Colin would depend on his long term savings.

The test organism ferments sucrose best under reduced oxygen conditions.
The sample was incubated less than 24 hours, which allowed for only limited fermentation.
The media was contaminated.
The organism is an obligate aerobe and therefore can only grow inside the Durham tube.
The media was prepared wrong.
The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.
The test organism did not ferment sucrose.
1)The test organism ferments sucrose best under reduced oxygen conditions.
2)The sample was incubated less than 24 hours, which allowed for only limited fermentation.
3)The organism is limited in its ability to ferment sucrose. Since diffusion is restricted within the Durham tube and it contains only a small volume of media, it turned yellow first.
