<prompt> In a study of 2000 population, mean value of hemoglobin is 13.5 gm, which follows normal distribution curve. Percentage of people having higher hemoglobin than 13.5 gm:5255075  <response>: Ans. c. 50In a population with normal distribution mean, median and mode are equal. So, here median is also 13.5, which divides the population into two equal halves. So, 50 will be on either side of 13.5. Hence, percentage of people having higher hemoglobin than 13.5 gm is 50.DistributionCentral TendencyNormal Gaussian DistributionMean Median ModeQ13.5 Median divides the population into two equal halves 50 will be on either side of 13.5.
