Step-by-step explanation:
Answer:
a) The total gross sales over the next 2 weeks exceeds $5000 is 0.0321.
b) The weekly sales exceed $2000 in at least 2 of the next 3 weeks is 0.9033.
Step-by-step explanation:
Given : The gross weekly sales at a certain restaurant are a normal random variable with mean $2200 and standard deviation $230.
To find : What is the probability that
(a) the total gross sales over the next 2 weeks exceeds $5000;
(b) weekly sales exceed $2000 in at least 2 of the next 3 weeks? What independence assumptions have you made?
Solution :
Let
and
denote the sales during week 1 and 2 respectively.
a) Let
Assuming that
and
follows same distribution with same mean and deviation.




So, 





The total gross sales over the next 2 weeks exceeds $5000 is 0.0321.
b) The probability that sales exceed teh 2000 and amount in at least 2 and 3 next week.
We use binomial distribution with n=3.





Let Y be the number of weeks in which sales exceed 2000.
Now, 
So, 



The weekly sales exceed $2000 in at least 2 of the next 3 weeks is 0.9033.
Answer:
- <u><em>x-int: (2, 0)</em></u>
- <u><em>y-int: (0, -5)</em></u>
To find the x-intercept, substitute in 0 for y.
To find the y-intercept, substitute in 0 for x.
