Let's take a look at D:

<span>D) y = (x-1)^2 - 16 Compare this to
y = (x-h)^2 + k This is the std. equation of a parabola in vertex form.

You can see, by comparison, that h=1 and k= -16; these are the coordinates of the vertex, clearly shown in the diagram.

Since the coefficient of (x-h)^2 is +1, the graph opens upward (which the given graph confirms), and is neither compressed nor stretched vertically.</span>

The director of a state agency believes that the average starting salary for clerical employees in the state is less than $30,00

Answer:

The test statistics is $z = -1$

Step-by-step explanation:

From the question we are told that

The sample size is n = 100

The null hypothesis is $H_o : \mu = \$30000$

The alternative hypothesis is $H_a : \mu < \$ 30000$

The sample mean is $\= x = \$29,750$

The standard deviation is $\sigma = \$2,500$

The level of significance is $\alpha =0.05$

Generally the test statistics is mathematically represented as

$z = \frac{\= x - \mu }{ \frac{ \sigma}{ \sqrt{n} } }$

=> $z = \frac{29750 - 30000 }{ \frac{ 2500}{ \sqrt{100} } }$

=> $z = -1$
