Answer:

Fourth Quadrant

Step-by-step explanation:

The point (2, -22) is located in the 4th quadrant because the x-value is positive (to the right of the y-axis) and its y-value is negative (down from the x axis)

B) A white shirt costs $. 2.50, and a blue shirt costs $. 1.50

djyliett [7]

<h3>Answer :</h3>

Cost of white shirt = 2.50 $

Cost of blue shirt = 1.50 $

We have asked to find percentage difference $.$

_________________________________

$:\implies\sf\:\dfrac{cost_{blue}-cost_{white}}{cost_{blue}+cost_{white}}\times 100$

$:\implies\sf\:\dfrac{2.50-1.50}{2.50+1.50}\times 100$

$:\implies\sf\:\dfrac{1}{4}\times 100$

$:\implies\:\boxed{\bf{\gray{25\:\%}}}$

Answer:

d. -5.666 to -0.926

Step-by-step explanation:

Here a pivotal quantity is $T = \frac{\hat{\beta_{1}}-\beta_{1}}{se(\hat{\beta_{1}})}$ where $\beta_{1}$ is the true slope of the regression equation (unknown), $\hat{\beta_{1}}$ is its least square estimate and $se(\hat{\beta_{1}})=1.097$ is its estimated standard error. And T has t-distribution with n-2=15-2=13 degrees of freedom (n is the sample size). We have that $\hat{\beta_{1}} = -3.30$ , and because we want the 95% confidence interval, we should use the 2.5th quantile of the t distribution with 13 df, this value is -2.16 and the 95% confidence intervale is given by $\hat{\beta_{1}}\pm t_{0.025}se(\hat{\beta_{1}})$ , i.e., $-3.30\pm (2.16)(1.097)$ . Therefore, the 95% confidence interval explicitly is (-5.666, -0.926)
