The speed with which utility companies can resolve problems is very important. In the United Kingdom, Octopus Energy reports it can resolve customer problems the same day they are reported in 70% of the cases. Suppose the 15 cases reported today are representative of all complaints. What is the probability 9 of the problems can be resolved today? Note: Round your answer to 3 decimal places. What is the probability 9 or 10 of the problems can be resolved today? Note: Round your answer to 3 decimal places. What is the probability more than 10 of the problems can be resolved today? Note: Round your answer to 3 decimal places.

Step 1
We are given that Octopus Energy can resolve customer problems the same day they are reported in 70% of the cases. We need to calculate the probability of resolving exactly 9, exactly 9 or 10, and more than 10 out of 15 reported problems in a day. Show more…

The speed with which utility companies can resolve problems is very important. GTC, the Georgetown Telephone Company, reports it can resolve customer problems the same day they are reported in 80% of the cases. Suppose the 14 cases reported today are representative of all complaints. What is the probability 6 of the problems can be resolved today? What is the probability 6 or 7 of the problems can be resolved today?

The speed with which utility companies can resolve problems is very important. GTC, the Georgetown Telephone Company, reports it can resolve customer problems the same day they are reported in 75% of the cases. Suppose the 13 cases reported today are representative of all complaints. How many of the problems would you expect to be resolved today? (Round your answer to 2 decimal places.) What is the standard deviation? (Round your answer to 4 decimal places.) What is the probability 10 of the problems can be resolved today? (Round your answer to 4 decimal places.) What is the probability 10 or 11 of the problems can be resolved today? (Round your answer to 4 decimal places.) What is the probability more than 8 of the problems can be resolved today? (Round your answer to 4 decimal places.)
