Answer:
range ={-6,-2,4,8}
Step-by-step explanation:
The given function is
The domain is given as:
domain = {-4,-2, 1,3}
To find the range, we plug in the domain and solve for the corresponding range value.
When x=-4,
When x=-2,
When x=1,
When x=3,
Therefore the range is {-6,-2,4,8}

Answer:
[ 1,532.41, 1,617.59]
Step-by-step explanation:
Data provided :
Sample size, n = 120
Mean = $1,575
Standard deviation = $215
Confidence level = 97%
Now,
Confidence interval = Mean ±
also,
for 97% confidence level z score = 2.17 [from standard z-table]
= $1,575 ±
= $1,575 ± 42.59
Therefore,
Confidence interval = [ $1,575 - 42.59, $1,575 + 42.59]
= [ 1,532.41, 1,617.59]
