The unit rate of the parachutist change in height is 11 feet per second.
• In Mathematics, Unitary method is a technique for solving a question by first finding the value of a single unit and then finding the required value by multiplying the number by value of single unit .
• We use unitary method to find the ratio of one thing with respect to other thing.
• There are two types of unitary method one is Direct Variation and the other is Inverse variation.
We have the rate of descend as 44 feet in 4 sec.
So, in 1 second it will be = 44 / 4 = 11 feet.
Which is the unit rate.
Therefore, the unit rate of descend for the parachutist is 11 feet per second.

The confidence interval can be calculated from the margin of error, and vice versa,
The margin of error of the confidence interval is 2.156
The confidence interval is given as:

The formula of confidence interval is:

Where E represents the margin of error.
So, by comparison:

Multiply

Hence, the margin of error of the confidence interval is 2.156
