Answer:

B - 2 hours

Step-by-step explanation:

find the rate for each scenario until you find one that matches.

for A 1 hour:

Ben charges (15.50×1hour) = 15.50

Cathie charges (9.25 × 1 hour) + 12.50 flat fee = 21.75

THESE DO NOT MATCH

so you do B 2 hours:

Ben charges 15.50× 2hours = 31

Cathie charges (9.25 × 2hours) + 12.50 flat fee = 31

THESE MATCH SO THIS IS THE ANSWER

If you continue like this for 3 hours and 4 hours the values don't match. so the only answer is B.

Arlecino [84]

Answer:

The claim is rejected

Step-by-step explanation:

Claim: UCF is advertising their bachelor in Economics with the statistic that the starting salary of a graduate with a bachelor in economics is $ 48,500 according to Payscale (2013-13).

Null hypothesis: $H_0: \mu = 48500$

Alternate hypothesis : $H_a : \mu \neq 48500$

n = 50

Since n is more than 30 .

So we will use Z test

x=43350

Standard deviation = 15000

$Z=\frac{x-\mu}{\frac{s}{\sqrt{n}}}\\Z=\frac{43350-48500}{\frac{15000}{\sqrt{50}}}\\Z=-2.42$

Refer the z table

p value = 0.00776

$\alpha = 0.01$

p value < $\alpha$

So, We are failed to accept null hypothesis

Hence The claim is rejected
