Answer:

Step-by-step explanation:

Since side BC = side AD (because opposite side of a parallelogram are congruent)

Angle C = angle A(because opposite angles of a parallelogram are congruent)

side DC = side AB(because the opposite sides of a parallelogram are congruent. Therefore,

aniked [119]

Answer:

The correct option is;

B. With 95 percent confidence, it can be said that the repair cost is between the bounds of the confidence interval

Step-by-step explanation:

Here we have the formula for confidence interval, CI given as follows;

CI=\bar{x}\pm t\frac{s}{\sqrt{n}}

Where:

\bar x = Sample mean = $90.00

s = Sample standard deviation = $14.00

n = Sample size = 5

t = z value for the confidence level = 2.7764 from z-score relations

Plugging in the values, we have;

CI=90.00\pm 2.7764 \frac{14.00}{\sqrt{5}}

Which gives the CI as 72.6167 to 107.38.
