In a simple regression analysis for a given data set, if the null hypothesis β = 0 is rejected, then the null hypothesis ρ = 0 i
kati45 [8]

Answer:

Null hypothesis: \rho =0

Alternative hypothesis: \rho \neq 0

The statistic to check the hypothesis is given by:

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

And is distributed with n-2 degrees of freedom

And the statistic to check the significance of a coeffcient in a regression is given by:

t_1 = \frac{\hat{\beta_1} -0}{S.E (\hat{\beta_1})}

For this case is importantto remember that t1 and p value for test of slope coefficient is the same test statistic and p value for the correlation test so then the answer would be:

Always

Step-by-step explanation:

In order to test the hypothesis if the correlation coefficient it's significant we have the following hypothesis:

Null hypothesis: \rho =0

Alternative hypothesis: \rho \neq 0

The statistic to check the hypothesis is given by:

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

And is distributed with n-2 degrees of freedom

And the statistic to check the significance of a coeffcient in a regression is given by:

t_1 = \frac{\hat{\beta_1} -0}{S.E (\hat{\beta_1})}

For this case is importantto remember that t1 and p value for test of slope coefficient is the same test statistic and p value for the correlation test so then the answer would be:

The diagram below shows an Isosceles triangle. Label the base angles and the vertex
Dmitry [639]

The base angles of an isosceles triangle are equal

The base angles are 15 degrees, while the vertex angle is 150 degrees

The base angles are given as:

Base = (6a- 3) and (a + 12)

So, we have:

\mathbf{6a -3 =a + 12}

Collect like terms

\mathbf{6a -a =3 + 12}

\mathbf{5a = 15}

Divide both sides by 5

\mathbf{a = 3}

Substitute 3 for a in Base = (6a- 3),

\mathbf{Base = 6 \times 3 - 3}

\mathbf{Base = 18 - 3}\\

\mathbf{Base = 15}

So, the base angle is 15 degrees.

The vertex angle is calculated using:

\mathbf{Vertex=180 -2 \times Base}

So, we have:

\mathbf{Vertex=180 -2 \times 15}

\mathbf{Vertex=150 }

Hence, the vertex angle is 150 degrees
