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.

Which expression is equivalent to 2^4 ⋅ 2^−7?
yaroslaw [1]
Remember
(x^m)(x^n)=x^{m+n}
and
x^{-m}=\frac{1}{x^m}

so
(2^4)(2^{-7})=
2^{4-7}=
2^{-3}=
\frac{1}{2^3}=
\frac{1}{8}

Find the length of a line segment CD with endpoint C at (-3,1) and endpoint D at (5,6)
lutik1710 [3]
I believe your length would be 8, because -3 to get to 0 is 3 then after that you still have 5 so you add them and get 8
