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.

White car in the left lane moving more slowly than the surrounding traffic is a violation of state uniform traffic law as such cars are meant to be on the right lane.
<h3>What is Traffic law?</h3>
These are the rules which regulate the movement of vehicles and other road users to ensure safety.
The car being on the left lane will impact the behavior of the other drivers on the roadway by impeding traffic and makes everyone less safe. This is therefore why it is not accepted and a violation.

Explanation:
The proportion of the drinks having the cost of more than 4 dollars in a coffee shop is two thirds.
<h3>What is a Uniform Density Curve?</h3>
Uniform Density Curve is given as the curve with the rectangle shape defining all the probabilities given for an outcome are identical.
The uniform density curve for the coffee shop have the been plotted as cost of drinks. The x-axis is the representation of the cost, and the plot is formulated one third from 3-6.
From the uniform density curve, the proportion of the drinks that are found to be costing in more than 4 dollars are two third, as one third lies for the cost up to 3 dollars.
