Sohal‚ S 04/05/11 (HLT-362 V) Applied Statistics for Healthcare Professionals Exercise 18 Q1. Assuming that the distribution is normal for weight relative to the ideal and 99% of the male participants scored between ( - 53.68‚ 64.64)‚where did 95% of the values for weight relative to the ideal lie? Round your answer to two decimal places. Answer: Mean of weight relative to ideal = 5.48 and Standard Deviation (σ) = 22.93. Calculation: (x bar) 1.96(σ) 5.48± 1.96(22.93) 5.48 - 1.96(22.93)

Age‚ income‚ length of labor‚ return to work‚ and number of hours working per week 2. What statistics were used to describe the length of labor in the study? Were these appropriate? Mean and standard deviation were used to describe the length of labor. Yes‚ these were appropriate because a mean (M) can only be used to calculate on interval (and
