A data is collected from Lab A, and this data is considered as the reference (standard). Sample mean is 12, SD is 2.4 and sample size if 16. Another set of data from Lab B have a mean of 10, SDB is 2.4 and nB=16. If we choose = 0.05, do you think mean of Lab B is close enough to be considered the “same” as that of Lab A? Why?

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

One side of a rectangle is 7 feet shorter than seven times the other side. find the length of the shorter side if we also know that the perimeter of the rectangle is 306 feet.
