1) 2678 cm into feet.

strojnjashka [21]

Set up multiplication/division of proportions to cancel out units that you don't want and to introduce units that you do want in your final solution...

2678cm(in/2.54cm)(ft/12in)=2678/30.48 ft≈87.86 ft (to nearest hundredth)

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

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

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

=> $z = -1$

Where would we find the point (–10,0)? A. Quadrant III B. y-axis C. Quadrant II D. x-axis

Elina [12.6K]

The answer is D. x-axis, because of the layout of (x,y), meaning there would be an x value of -10, but no y value so it would sit on the x-axis
