Final answer:
The question concerns the probability of employees making more than an average number of calls, which requires statistical analysis. As critical information for the calculation is missing, a specific probability cannot be determined. The claim that measuring call time is always key to efficiency and loyalty is too simplistic and can be false.
Step-by-step explanation:
The question pertains to the probability of a certain event in a business context, which is the likelihood that employees will make more than the average number of long-distance phone calls during peak time. To calculate this probability, one would typically use concepts from statistics. However, without more information such as the distribution or variance of the calls, we cannot provide a specific answer. The statement regarding the measurement of time spent by employees on telephone contacts being key to efficiency and loyalty is an oversimplification and could be false, as loyalty and efficiency are influenced by a wide range of factors, and focusing solely on phone contact time might not address other crucial aspects of employee performance and satisfaction.
