Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

f(x) = 3 | x + 6 | + 9

Represents a horizontal shift of the parent function 6 units left

mr Goodwill [35]

Answer:

Step-by-step explanation:

The null and the alternative hypothesis are:

\mathbf{ H_o: \rho = 0} \\  \\ \mathbf{H_1: \rho \ne 0}

The test statistics is as follows:

t =  \dfrac{r\sqrt{n-2} }{\sqrt{1-r^2}}

t =  \dfrac{0.4 \sqrt{30-2} }{\sqrt{1-0.4^2}}

t =  \dfrac{0.4 \sqrt{28} }{\sqrt{0.84}}

t = 2.3094

The critical value

t_{\alpha/df} =  t_\ \{0.05/2 \  , \  30-2 \} }  \\ \\  = t_{0.025,28} = \pm 2.048 ( from \ the \ t-tables)

Decision rule:

To reject H_o if t > t_{\alpha/df}.

So since t > t_{\alpha/df}. we reject H_o at ∝ = 0.05

Conclusion: There is sufficient evidence to conclude that blood pressure and patient calcium are linearly related.
