This document of This pack of QNT 351 Week 4 Discussion Question 2 comprises: contains: Why does the significance level differ among industries? Will the null hypothesis be more likely to be rejected at ? = 0.01 than ? = 0.10? As the significance level increases to ? = 0.10 from ? = 0.01‚ which type error is more likely to occur? What can be done to reduce the likelihood of incurring this error? Deadline: ( )‚ Business - General Business I need tutorials from week 1-5 with all assignments

1 Measures of Central Tendency “Measures of central tendency (averages) are statistical constants which enable us to figure out in a single effort the significance of the whole.” (Prof Bowley) The main objectives of measure of central tendency are To reduce data in a single value. To make easy comparisons between data. There are different types of averages; each has its own business applications. 1. Arithmetic Mean 2. Median 3. Mode 4. Geometric Mean 5.
