the area of a room in a dollhouse is 1248 square inches. the width of the room is 8 inches. how long is the room

zaharov [31]

The dollhouse is 156 inches long.

Area is computed by multiplying the length to its width.

A = L * W

Use the formula and substitute the values given in the problem.
A = 1248 sq. inches
w = 8 inches
L = ?

1248 = L * 8

L = 1248 sq. in/ 8 in
L = 156 inches

Answer:

2.083 < µ1 - µ2 < 5.917

Step-by-step explanation:

We will need to construct a 90% confidence interval for the difference of 2 means where the populations are normally distributed, and their variances are equal.

The calculations of the sample means and standard deviations are done for us.

Sample 1: Catalyst 1

n = 12, x = 85, s = 4

Sample 2: Catalyst 2

n = 10, x = 81, s = 5

See attached photo for the construction of the confidence interval...
