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

ss7ja [257]

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

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

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

=> $z = -1$

Algebra help

Vilka [71]

To determine the correct ordered pairs which will agree with the function, we can substitute values to the function and see whether it agree with each other. We do as follows:

(0,1)
 f(x)=128(0.5)^0
 f(x)=128

(1,64)
 f(x)=128(0.5)^1
f(x) = 64 <--------CORRECT ANSWER

(3,16)
 f(x)=128(0.5)^3
f(x) = 16 <--------CORRECT ANSWER

(8,0.5)
 f(x)=128(0.5)^8
f(x) = 1/2

Hope this answers the question. Have a nice day.
