Find the dimensions of a rectangular building with a perimeter of 110 meters if the length is four

Mathematics

Answer:

b = 11 m

l = 44 m

Step-by-step explanation:

l = 4b (length is four times width)

Perimeter = 110 m

2 * ( l + b ) = 110

2 * (4b + b ) = 110

         2 * 5b = 110

                b = 110 / ( 2*5) = 11

b = 11 m

l = 4b = 4 * 11 = 44 m

A random sample of 87 eighth grade students’ scores on a national mathematics assessment
Finger [1]

There is not enough evidence to support the administrator’s claim and the true mean is not significantly greater than 280.

<h3>What is a statistical hypothesis?</h3>

A hypothesis to test the given parameters requires that we determine if the mean score of the eighth graders is more than 283, thus:

The null hypothesis:

\mathbf{H_o \leq 283}

The alternative hypothesis:

\mathbf{H_i > 283}

From the population deviation, the Z test for the true mean can be computed as:

\mathbf{Z = \dfrac{\hat X - \mu _o}{\dfrac{\sigma}{\sqrt{n}}}}

\mathbf{Z = \dfrac{283 -280}{\dfrac{37}{\sqrt{87}}}}

Z = 0.756

Note that, since we are carrying out a right-tailed test, the p-value for the test statistics is expressed as follows:

P(z > 0.756)

P = 0.225

Since the P-value is greater than the significance level at α = 0.14, we can conclude that there is not enough evidence to support the administrator’s claim and the true mean is not significantly greater than 280.
