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: 
Alternate hypothesis :
n = 50
Since n is more than 30 .
So we will use Z test
x=43350
Standard deviation = 15000

Refer the z table
p value = 0.00776

p value < 
So, We are failed to accept null hypothesis
Hence The claim is rejected

Answer:
x = 0 and x = 6
Step-by-step explanation:
See the graph attached to this question.
It is clear from the graph that the curve touches x-axis i.e. y becomes zero at points x = 0 and x = 6
Therefore, the give parabola has zeros at x = 0 and x = 6. (Answer)
Zeros of a function y = f(x) are determined from the equation f(x) = 0 and solving it we will get the x-values which are the zeros of the function.
