Answer:
Their cost is difficult to estimate and people take them for granted.
Explanation:
Ecosystem services are rarely included in economic analysis because people usually take them for granted and their cost is difficult to estimate.
if an independent-measures study uses n = 15 participants in each group to compare two treatment conditions. then 28 is the df value for the t statistic for this study.
The t-statistic, which is used in statistics, measures how far a parameter's estimated value deviates from its hypothesised value relative to its standard error. Through the Student's t-test, it is utilised in hypothesis testing. In a t-test, the t-statistic is used to decide whether to accept or reject the null hypothesis. The t-statistic is used when the sample size is small or the population standard deviation is unknown. It is quite similar to the z-score in other respects. Once the standard deviation is unknown, the t-statistic is in use, for one, to approximate the population mean from a sampling distribution of sample statistics.

<em>An arch is formed by process of erosion which can be played by wind, water flow or other elements.</em>
<em>The dam affects the movement of sediment by preventing and controlling the flow of the solids. </em>
<em>Wall Arch is normally a rock curved shaped as with an opening underneath it.</em>
<em>Erosion, mass wasting and weathering are three process that cause Wall arch collapse.</em>
<em>One way gravity helps glaciers shape landforms is by attracting the glacier to lower elevations, the glacier then freeze out close lands and soil and rock will stick to it, again gravity then helps the glacier move quickly, because it became heavier with the new agglomerated mass.</em>
Answer:Risky Shift Phenomenon
Explanation:
There are decisions that seem easier to take when we are not taking them alone, we may even take a risk in groups that we wouldn't take if we were doing it individually. This occurs because we know that the risk is shared amongst everyone in a group , which decreases individual risk. This is what is called a risky shift.
This means even the most cautious person may loosen up a bit and be willing to take a risk if they are in company of others. Sometimes the Risky Shift may also occur because you don't want to let your friend down or dissapoint them when they suggest something risky.
Sometimes high risk takers may be very influential such that you may find yourself willing to take a risk with them.
