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,

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

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

Step-by-step explanation:

Formula for SA of a rectangular prism:

SA = 2lh + 2lw + 2wh

Given dimensions:

l = 1

w = 7

h = 6

Simply plug in these given dimensions into the SA formula to get the answer

SA = 2lh + 2lw + 2wh

Substitute given variables

SA = 2(1)(6) + 2(7)(1) + 2(6)(7)

* Multiply parentheses that are next to each other *

SA = 2(6) + 2(7) + 2(42)

* Multiply again *

SA = 12 + 14 + 84

*add*

SA = 110
