Question

A web-based travel search engine is designed to complete searches for cruise ships involving price retrieval and scheduling information. You need to analyze how long it takes to complete a typical search. The search time for 2500 randomly selected searches is recorded and determined as sample mean = 0.94 seconds and sample standard deviation = 0.36 seconds. Choose the most typical value for C and provide the confidence interval.

The important question is can this question be answered?? Our teacher is very tricky so I just want to make sure that this problem can be solved, or cannot (because not enough information was provided).

Answer 1

Sample size, n= 2500 Sample mean a = 0094 sample so 3 = 0.36. If 'c' value is not mentioned, are generally consider, d=0.05 are fad 95% confidence interval ... is 95% confidence internal for mean search time of all cause shape is [ñ-1.96x8, x+1=96x8] [2x = 1.96] & (0.94-1996x 0.36 , 0.94+1096%0.36 1 (2500 - (0.92.59, 0.9541) CO.93, 0095) in wir 95th confidence, cue can couche de that the population mean search time of all cruise ship de envolung price retnewal and scheduling information has betures [0.93 seconds and 10.95 seconds . 12500 0.93 < l< 0.95
