Answer:

$y=-\frac{2}{5}+100$

Step-by-step explanation:

With the given information, we can write the line equation in slope intercept form. $y=mx+b$

The slope, m, is -2/5

The Y-intercept, or b, is 100.

Replace m with -2/5 and b with 100.

$y=mx+b\\y=-\frac{2}{5}x+100$

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

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

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

=> $z = -1$
