A landscaping company charges customers for lawn care based on the area of their yards. Mr. Jones was charged $52 for his yard,
crimeas [40]

Answer:

Landscaping Company will charge $80 for Neighbor yard.

Step-by-step explanation:

Given:

Charges of Mr. Jones = $52

Length of Mr. Jones yard = 65 feet

Width of Mr. Jones yard = 40 feet

Now we will find the area of Mr. Jones yard.

Yard is basically in rectangular form.

Hence we can;

Area of yard is equal to product of length of the yard and width of the yard.

Framing in equation we get;

Area of Mr. Jones Yard = 40\times 65 = 2600\ ft^2

Now Mr. Jones was charged $52 for a yard having Area 2600 sq. ft.

So we will find the per sq. ft charge applied by the company.

Per sq. ft charge will be equal to Charges of Mr. Jones divided by Area of Mr. Jones Yard.

Framing in equation form we get;

Per sq. ft charge = \frac{52}{2600} = \$0.02

Hence the Landscaping company charge Mr. Jones at $0.02 per sq.ft.

Now Given:

Length of Neighbor yard = 80 ft.

Width of Neighbor yard = 50 ft.

We need to find the Charges on Neighbor based on charges applied on Mr. Jones.

First we will find the Area of Neighbors yard we get;

Area of Neighbors yard = 80 \times50 = 4000\ ft^2

Charges of Neighbor yard will be equal to charges Landscaping company for per sq. ft multiplied by area of Neighbors yard.

Framing in equation form we get;

Charges of Neighbor yard = 0.02\times 4000 = \$80

Hence Landscaping Company will charge $80 for Neighbor yard.

The​ quality-control manager at a compact fluorescent light bulb​ (CFL) factory needs to determine whether the mean life of a la
Taya2010 [7]

Answer:

The mean life of a large shipment of CFL bulbs is equal to 7,520 hours.

Step-by-step explanation:

The quality control manager wants to determine whether the mean life of a large shipment of CFL bulbs is equal to 7,520 hours.

The quality control manager can use a one-sample test to determine whether the mean life is 7,520 hours or not.

The hypothesis can be defined as follows:

<em>H₀</em>: The mean life of a large shipment of CFL bulbs is equal to 7,520 hours, i.e. <em>μ</em> = 7520.

<em>Hₐ</em>: The mean life of a large shipment of CFL bulbs is different from 7,520 hours, i.e. <em>μ</em> ≠ 7520.

The information provided is:

\sigma=1200\\n=64\\\bar x=7324

As the population standard deviation is provided, we will use a <em>z</em>-test for single mean.

Compute the test statistic value as follows:

z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}=\frac{7324-7520}{1200/\sqrt{64}}=-1.31

The test statistic value is -1.31.

Decision rule:

If the <em>p</em>-value of the test is less than the significance level then the null hypothesis will be rejected.

Compute the <em>p</em>-value for the two-tailed test as follows:

p-value=2\times P(Z

*Use a <em>z</em>-table for the probability.

The <em>p</em>-value of the test is 0.1902.

The <em>p</em>-value of the test is very large for all the commonly used significance level. The null hypothesis will not be rejected.

Thus, it can be concluded that the mean life of a large shipment of CFL bulbs is equal to 7520 hours.
