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.

3x-4(2+3x)=82
enyata [817]

Answer:

x=-10

Step-by-step explanation:

3x-4(2+3x)=82

3x-(4*2)+(4*3x)=82

3x-8-12x=82

-9x-8=82

-9x-8+8=82+8

-9x=90

-9x/-9=x

90/-9=-10

x=-10

Help please!! What is the slope?
Brut [27]

Answer:

C. -1/3

Step-by-step explanation:

Youre getting close here!

since you are rising by one, and running by 3, the slope will be 1/3

BUT this is a negative slope, the line is going <em>down</em>

that means, the slope will be negative.

the slope is C. -1/3
