<u>Given system:</u>
<u>Multiply the first equation by 7 and add up the equations:</u>
- -7x + 7y + 7x + 3y = 7*8 - 16
- 10y = 40
- y = 4
<u>Find y:</u>
Answer:
The z-value rounded to the nearest hundredth is -1.64
There is no enough evidence to reject the claim.
Step-by-step explanation:
A certain website claims that it averages 4.7 hours of downtime per month.
No. of samples = n = 17
Mean =
Standard deviation =
Formula:
Z =−1.64
Z critical at 90% is 1.65
Since Z calculated < Z critical
So, there is no enough evidence to reject the claim.
