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:
16
Step-by-step explanation:

Answer:
7.
Step-by-step explanation:
21 = 3 * 7
28 = 2 * 2 * 7
42 = 2 * 3 * 7
Collecting common factors:
t is common to all 3 sets of factors so
HCF = 7.
Answer:
The slope is 2. (m=2).
Step-by-step explanation:
y+5=2x+2
y+5-5=2x+2-5
y=2x-3
Equation is y=2x-3.
y=y-intercept
x=slope
Hence, the slope is 2.
Hope this helps and stay safe!
