Basic Statistics - Old Questions

1. There are two popular Cyber Café’s (namely Café A and Café B) in Kathmandu located at Thamel area. Each of them has good number of computers in the cyber and maintains peace, comfort and good working environment. Each costumer, before entering into the café, asks to the café owner about the average time to download an image file since the internet in Kathmandu is a bit of sporadic. Each of them replied that the time to download an image file is on an average no more than 70 seconds. The following is the data of downloading time for an image file experienced by 8 customers in each café in some random 8 different days. 

a) Explain whether the owner’s response to the costumers are satisfied in each café? Even having the average waiting time within the owner’s limit, is there any further comments on the data with reference to measures of central tendency you have computed? Discuss.

b) What similarities and differences are observed based on the average download time in Café A and in café B?

c) Compare the download time between two café’s with respect to variability and shape of the data distribution.

d) On the basis of your statistical analysis, which café would be suggested to the customers so that one can download an image file in a lesser time?
