Answer:

A)28

B)67.45

C)71.4  

Step-by-step explanation:

We are given the following data:

68,63,67,66,65,87,69,61,86,82,28

a) The outlier in the data is 28 as we can clearly see all the data points in the given data set ranges from 60 to 88 but their is a single entry of 28 which is different.

b) Mean = \frac{\text{Sum of all observations}}{\text{Total number of observations}}\\\\ = \frac{68+63+67+66+65+87+69+61+86+82+28}{11}\\\\=\frac{742}{11} = 67.45

c)Mean = \frac{\text{Sum of all observations}}{\text{Total number of observations}}\\\\ = \frac{68+63+67+66+65+87+69+61+86+82}{10}\\\\=\frac{714}{10} = 71.4

The outlier is 28 because there is a big gap between 28 and 61

to find the mean add all the numbers together then
divide the number of values added

Suppose you are the manager of Speedy Oil Change which claims that it will change the oil in​ customers’ cars in less than 30 mi
Veronika [31]

Answer:

Explained below.

Step-by-step explanation:

(1)

The hypothesis can be defined as follows:

<em>H</em>₀: The Speedy Oil Change will change the oil in​ customers’ cars in more than 30 minutes on average, i.e. <em>μ</em> > 30.

<em>H</em>ₐ: The Speedy Oil Change will change the oil in​ customers’ cars in less than 30 minutes on average, i.e. <em>μ</em> ≤ 30.

(2)

Use Excel to compute the sample mean and standard deviation as follows:

\bar x=\text{AVERAGE(array)}=24.917\\\\s=\text{STDEV.S(array)}=8.683

Compute the test statistic as follows:

t=\frac{\bar x-\mu}{s/\sqrt{n}}=\frac{24.917-30}{8.683/\sqrt{36}}=-3.51

The degrees of freedom is:

df = n - 1

   = 36 - 1

   = 35

Compute the p-value as follows:

p-value=P(t_{35}

(3)

The <em>p</em>-value = 0.0006 is very small.

The null hypothesis will be rejected at any of the commonly used significance level.

(4)

There is sufficient evidence to support the claim that the Speedy Oil Change will change the oil in​ customers’ cars in less than 30 minutes on average.

Name the Solid.​
Mila [183]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

base = 11 km

height 1 = 7 km

height 2 = 10 km

a) Name of the solid = Triangular prism

b) The base is a triangle

c) Volume

Formula

Volume = 1/2 base x height 1 x height 2

-Substitution

Volume = 1/2 (11) x (7) x (10)

-Simplification

Volume = 1/2(770)

-Result

Volume = 385 km³
