Problem 14.5

An information retrieval system has ten storage locations. Information has been stored with the expectation that the long-run proportion of requests for location i is given by pi (5.5 i 5.5)/30. A sample of 200 retrieval requests gave the following frequencies for locations 110, respectively: 4, 15, 23, 25, 38, 31, 32, 14, 10, and 8. Use a chisquared test at significance level .10 to decide whether the data is consistent with the a priori proportions (use the P-value approach).

Step-by-Step Solution:
Step 1 of 3

ST 260 Chapter 5 Note. Part 1 – 2/10/14 Prof. Cali Davis Quick Recall: ­ Quantitative Variables: differences that have meaning to them, such as age, income, height, and weight. ­ Qualitative Variable (OR categorical): putting people or things into classifications. Such as: gender, race, occupation, country, or political affliction. Statistics can be described as “the science of decision­making in the face of uncertainty” (An educated guess) So how do we measure uncertainty ­ Using probability: A numerical value or measure of the LIKLIHOOD that a certain outcome or event occurs. P(A)= probability of eventA
