Answer:
Option c.
Step-by-step explanation:
Confidence interval refers to an interval such that there is a probability that the value of a parameter lies within that interval.
Therefore, the confidence interval of the mean means that there is a probability that the value of a parameter lies within that confidence interval.
So, option c. is correct
In the picture below, h is height of building and x is the distance the base of the ladder is away from the base of the building.
We use trigonometry to find x, particularly the cosine function.
cos(29.37°) = x/32
cos(29.37°)(32) = x
27.8870633052 = x
We now round off to the nearest hundredths, which means to two decimal places.
27.89 feet = x
