Answer:
The probability that you have the disease, given that your test is positive is ≈ 0.0098
Explanation:
This is a conditional probability problem.
Let P(A|B) denote the conditional probability of A given B and it satisfies the equation
- (1) P(A|B) = P(A) × P(B|A) / P(B)
We have the the probabilities:
- P(Testing Positive | Having Disease) =0.99
- P(Testing Negative | Not Having Disease) =0.99
- P(Testing Positive | Not Having Disease) = 1-0.99=0.01
- P(Having Disease) = 0.0001 (striking only one in 10,000 people)
- P(Not Having Disease)= 1 - 0.0001 = 0.9999
<u>We can calculate</u>:
P(Testing Positive) =
P(Having Disease) × P(Testing Positive | Having Disease) + P(Not Having Disease) × P(Testing positive | Not Having Disease ) = 0.0001×0.99 + 0.9999×0.01 =0.010098
<u>from </u><u>(1) </u><u>we have the equation</u>:
P(Having Disease|Testing Positive)=P(Having Disease) × P(Testing Positive | Having Disease)/ P(Testing Positive) = 0.0001×0.99/0.010098≈0.0098
Thus, the probability that you have the disease, given that your test is positive is ≈ 0.0098
Answer:
1. More access to data
2.convenience
3. Easy creation of BI solutions
4. Report creation
5. Saves time
Explanation:
A data warehouse can be described to be an electronic storage system that contains large amount of facts and information which sources for and also maintains data from different sources; either external or internal.
The most important reason for a data warehouse is for it to store great amounts of data to be used for query and also to be used for analysis.
Why do we use a data warehouse?
1. Users have more access to data due to the integration of various sources of data. It makes use of real time data facts
2. You can conveniently store and also create metadata
3. Business intelligence solutions can easily be created using data warehouses.
4. Users can easily create their own reports
5. Data warehouses makes accessing different data sets faster. It is a time saver as business users are not going to spend time trying to retrieve data from various sources.
