Answer:
the number of callers on average are in the system at any given time is 440
Step-by-step explanation:
Given that
The calls that arrive in a call center have an average rate of 100 per min
But it we involve the waiting time so the call needed 4.4 minutes
We need to to find no of callers are in the system at any given time
SO,
= 100 per min × 4.4
= 440
hence, the number of callers on average are in the system at any given time is 440
The same would be considered
Answer:
Because it increases the risk of Type 1 error
Step-by-step explanation:
ANOVA is the analysis of the variance .
When comparing more than two treatment means we use ANOVA because a t test increases the risk of type 1 error .
For example if we wish to compare 4 population means there will be 4C2 = 6 separate pairs and to test the null hypothesis that all four population means are equal would require six two sample t test. Similarly to test 10 population mean would require 45 separate two sample t test.
This has two disadvantages .
First the procedure is too lengthy and tediuos.
Second the overall level of significance greatly increases as the number of t- tests increases.
The analysis of the variance compares two different estimates of variance using the F distributionto determine whether the population means are equal.
