Question

Customers experiencing technical difficulty with their Internet cable hookup may call an 800 number for technical support. It takes the technician between 90 seconds to 13 minutes to resolve the problem. The distribution of this support time follows the uniform distribution.

(a) What are the values for a and b in minutes? (Do not round your intermediate calculationsRound your answer to 1 decimal place.)

Answer 1

The values for 'a' and 'b' representing the minimum and maximum support times for the uniform distribution are 1.5 minutes and 13 minutes respectively, after converting 90 seconds to 1.5 minutes.

Step-by-step explanation:

To find the values for a and b, which represent the minimum and maximum support time for a technical support call respectively, we use the information given about the uniform distribution of times from 90 seconds to 13 minutes.

First, we need to convert the timing from seconds to minutes. Since there are 60 seconds in 1 minute, 90 seconds is equal to 90/60 = 1.5 minutes.

Therefore, the values for a and b in minutes are:

• a = 1.5 minutes (minimum support time)
• b = 13 minutes (maximum support time)
