atroni [7]

Answer:

The width of the confidence interval is going to be wider

Step-by-step explanation:

When we Increase the level of confidence without changing the sample size the width of the confidence interval is going to be affected in the following way;

The margin of error (M.E) is going to be larger or be increased. This increase is due to the fact that the critical value is going to increase. Then the increased margin of error would cause the width of the confidence interval to become wider.

This answers your question.

Find an equation in standard form for the hyperbola with vertices at (0, ±10) and asymptotes at y = ± five divided by six times
blagie [28]
Refer to the diagram shown below.

In the diagram, the two vertices are located at (0, a) and (0, -a).
The equation for the parabola is
\frac{y^{2}}{a^{2}} -  \frac{x^{2}}{b^{2}} =1
The asymptotes have the equations
y= \pm \frac{a}{b} x

For the given problem,
The vertices are located at (0, +/-10).
Therefore a = 10.

The asymptotes are
y = \pm  \frac{5}{6} x
Therefore
\frac{a}{b} = \frac{10}{b} = \frac{5}{6} \\\\ 5b = 60 \\\\ b =12

Answer:
The equation of the parabola is
\frac{y^{2}}{100} - \frac{x^{2}}{144} =1
