Answer:

z = -0.57

Step-by-step explanation:

A z-score indicates how much away is something from the mean so it can be more(above) than the mean or less(below) than the mean.

sampling distribution mean = 0.03

standard error = 0.007

researcher's sample mean = 0.026

z = (0.026 - 0.03)/0.007

z = (-0.004)/0.007

z = -0.57

So that means the researcher's sample mean is 0.57 standard deviation below the sampling distribution mean.

The negative sign above is the indicator of below the mean value.

The area of the remaining board is [(L × B) - (l × b)].

According to the statement

We have to find that the area of the remaining board.

So, For this purpose, we know that the

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.

From the given information:

Suppose the bigger rectangle is labelled as ABCD and the smaller rectangle is labelled as PQRS.

And

Consider that the length and breadth of the bigger rectangle are L and B respectively. And the length and breadth of the bigger rectangle are l and b respectively.

The area of any rectangle is:

Area = Length × Breadth

The area of the bigger rectangle is:

Area of ABCD = L × B

The area of the smaller rectangle is:

Area of PQRS = l × b

Then the area of the remaining board will be:

Area of remaining board = Area of ABCD - Area of PQRS

Area of remaining board= (L × B) - (l × b)

Thus, The area of the remaining board is [(L × B) - (l × b)].
