Name: Ashley Lee Class: HLT-362 Applied Statistics for Healthcare Professionals Date: 04/01/2015 EXERCISE 18 • Mean, Standard Deviation, and 95% and 99% of the Normal Curve 1. 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. In order to find where 95% of the values for the weight of relative to the ideal lies you would use the formula that is presented in the text on page 132 of Exercise 18. This formula is:. The = MEAN (5.48) and the (SD) =Standard Deviation (22.93). These numbers were derived from table 1 on pg.133 under the column…show more content…
To find the 95% of the men’s scores you would again use the formula:. The Mean=52.53 and the SD=30.90. These scores were found on pg. 134 in table 2 column labeled Male in the pain category. Formula: 52.53±1.96(30.90) 52.53-1.96(30.90) = 52.53-60.56 52.53-60.56= -8.03 52.53+1.96(30.90) = 52.53+60.56 52.53+60.56= 113.09 ANSWER= (-8.03,113.09) 5. Were the body image scores significantly different for women versus men? Provide a rationale for your Answer. On pg. 133 of the workbook Exercise 18 the body image scores were found to be significantly higher in women versus men. The rationale for this information was stated in the information provided on pg.133 stating that women had a score of (73.1±17.0) and men had a score of (60.2±17.0). 6. Assuming that the distribution of Mental Health scores for men is normal, where are 99% of the men’s mental health scores around the mean in this distribution? Round your answer to two decimal places. To find the 99% of the men’s mental health scores you would use the formula:. This formula was found on page 132 of Exercise 18 in the second paragraph. The Mean=57.09 and the SD=23.72. These scores were found on pg. 134 in table 2 column labeled Male in the mental health category. Formula: 57.09±2.58(23.72) 57.09-2.58(23.72) = 57.09-61.20 57.09-61.20= -4.11 57.09+2.58(23.72) = 57.09+61.20 57.09+61.20= 118.29 ANSWER=
