Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Average number of arrivals = 6 per hour
Service rate = 3 every 15 minutes
Service rate is given by

So, the average number of customers in the system is given by

Hence, Option 'c' is correct.
#2. (-10, 0) (-10, -8) (0, -8)
#3. (-10, 0) (-10, 8) (-7, 8)
#4. (-10, 0) (-7, 0) (-7, 8)
#8. (0, 8) (0, 0) (8, 0) (10, 4)
#9. (-7, 0) (-7, 8) (0, 8) (0, 0)
#10. (-10, 0) (0, 0) (0, -8)
Not sure about the others. Hope this helps, though.
You do the same as with number you take out the largest allowed amount. For example for 8 you could take out x^2 and y^2 along with the normal factors, So once you factor everything out you would be left with 27x^2y^2(y^3-3x)
Answer:
The hypothesis should be retained
Step-by-step explanation:
We are given:
N= 16
n = 4


Level of significance, a = 0.05
From the given data, our ANOVA table will be:




Note: proper ANOVA table is attached
The statistic will be written as:

T = 8/4 = 2
Therefore


The hypothesis should be retained, because we no know that the statistic is in the acceptance area.
