The average cost of tuition, room and board at small private liberal arts colleges is reported to be $8,500 per term, but a fina
Vlada [557]

Answer:

The test statistic for this test is 3.82.

Step-by-step explanation:

The null hypothesis is:

H_{0} = 8500

The alternate hypotesis is:

H_{1} > 8500

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation of the population and n is the size of the sample.

In this question:

X = 8745, \mu = 8500, \sigma = 1200, n = 350

So

t = \frac{8745 - 8500}{\frac{1200}{\sqrt{350}}} = 3.82

The test statistic for this test is 3.82.

Which of the following absolute value equations has no solutions?Group of answer choices
Amiraneli [1.4K]

The absolute value measures the distance a number is away from the origin (zero) on the number line. A number can be to the left or right of zero on the number line, but the distance away from zero is always positive. Graphically:

In other words:

• If d is positive and

\begin{gathered} |x|=d \\ \text{ then} \\ x=d\text{ or }x=-d \end{gathered}

• If d is negative and

\begin{gathered} |x|=-d \\ \text{then} \\ \text{ No solution, because distance (d) can not be negative.} \end{gathered}

Therefore, the equation that has no solutions is:

\boldsymbol{|x|=-3}
