Answer:

Confidence Interval: (0.44,1.00)

Step-by-step explanation:

We are given the following data set:

0.60, 0.74, 0.09, 0.89, 1.31, 0.51, 0.94

Formula:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{:5.08}{7} = 0.725$

Sum of squares of differences = 0.8809

$S.D = \sqrt{\frac{0.8809}{6}} = 0.383$

90% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 6 and}~\alpha_{0.10} = \pm 1.943$

$0.725 \pm 1.943(\frac{0.383}{\sqrt{7}} ) =0.725 \pm 0.2812 = (0.44,1.00)$

No, it does not appear that there is too much mercury in tuna sushi.

A mountain climber started at sea level and descended down a cliff. Her location can be represented by -75 feet. How many feet d

mariarad [96]

The mountain climber has travelled 75 feet below sea level while descending down a cliff.

Given:

A mountain climber at sea level starts descending down a cliff.
Her location can be represented by -75 ft.

To find:

The distance travelled by a mountain climber.

Solution

Distance ascending above sea level is taken in a positive direction.
Distance descending down sea level is taken in a negative direction.
This negative and positive only represents the direction

The location of mountain climber after descending from cliff = -75 ft

The distance covered by the mountain climber = 75 ft

The mountain climber has travelled 75 feet below sea level while descending down a cliff.

Find the volume of the prism.

gtnhenbr [62]

Answer:

66 $cm^{3}$

Step-by-step explanation:

Vol = Bh where B is the area of the base and h is the distance between the bases (height)

The base is a right triangle and has an area of

B = 1/2bh = 1/2(4)(3) = 6

h = 11

V = 6(11) = 66 $cm^{3}$

select the correct answer from each drop-down menu. How are confidence intervals affected by interval size? When creating a conf

11111nata11111 [884]

<h3>Answer:</h3>

When creating a confidence interval, higher confidence corresponds to a <u> larger </u> interval, and lower confidence corresponds to a <u> smaller </u> interval.

==============================================

Explanation:

Imagine you are going fishing for an elusive sea creature of some kind. Casting a very wide net means we are more confident in catching the creature, in comparison to using a smaller net.

The fishing net is analogous to the width of the confidence interval. The wider the confidence interval, the more confident that we're capturing the parameter we're trying to measure.
