so all you need to do is take each point on the graph and add 2 to the y coordinate and add 5 to the x. you so this because it says up and to the right. hope this helps
Answer:
The 90% confidence interval is 0.575 to 0.625.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of 
.
For this problem, we have that:
90% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval is 0.575 to 0.625.
Answer:
UNIF(2.66,3.33) minutes for all customer types.
Step-by-step explanation:
In the problem above, it was stated that the office arranged its customers into different sections to ensure optimum performance and minimize workload. Furthermore, there was a service time of UNIF(8,10) minutes for everyone. Since there are only three different types of customers, the service time can be estimated as UNIF(8/3,10/3) minutes = UNIF(2.66,3.33) minutes.
The answer is A ∪ B = {2, 4, 5, 6, 8, 10, 12}
A = {2, 4, 6, 8, 10, 12}
B = {5, 10}
A ∪ B. The union of two sets is everything in both sets. So we will combine the outcomes in set A and set B. Since in set B 10 is an even number, we will just add number 5 in <span>A ∪ B.
</span>
A ∪ B = {2, 4, 5, 6, 8, 10, 12}

think its 1.10? tbh thats probably wrong
