A drug company is testing a new drag which is supported to reduce blood pressure. From the nine people who are used as subjects,
Pie

Answer:

The 95% confidence interval for the mean change in blood pressure, \bar{x}, is 1.744 < \bar{x} < 2.816

Step-by-step explanation:

The parameters given are;

The number of people in the sample, n = 9

The average drop in blood pressure, \bar{x} = 2.28 points

The standard deviation, σ = 0.82

The confidence level = 95%

The formula for confidence interval with a known mean is given as follows;

CI=\bar{x}\pm z_{\alpha/2} \dfrac{\sigma}{\sqrt{n}}

Where:

z_{\alpha/2} = z - score at 95% confidence level = 1.96

We therefore have;

CI=2.28 \pm 1.96 \times \dfrac{0.82}{\sqrt{9}}

Which gives the 95% confidence interval for the mean change in pressure, \bar{x}, is given as follows;

1.744 < \bar{x} < 2.816

Stells [14]

Answer:

Step-by-step explanation:

Students use algebra to solve equations (of the form px + q = r and p(x + q) = r where p, q, and r are specific rational numbers); using techniques of making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse) to solve for the variable.

Students identify and compare the sequence of operations used to find the solution to an equation algebraically, with the sequence of operations used to solve the equation with tape diagrams. They recognize the steps as being the same.

Students solve equations for the value of the variable using inverse operations; by making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse).
