PHE5IST: BIOSTATISTICS ASSIGNMENT2Answer 1Part AThe histogram given in the question describes that the distribution of the calcium intakesfor women of age between 51 and 80 years participating in the study of the bone health ofwomen is positively skewed. This means that most women intakes less amount of calcium thanthe average intake. Part BDaily Intake of CalciumMean941.82Median845Range2059Standard Deviation448.62Variance201262.75Standard Error72.78Part CThe 95% confidence interval for the mean is given by ́X±t×σ√n. Here, ́X is the mean, nis the sample size, t is the critical value of the t statistic at 95% confidence interval, σ is thestandard deviation of the sample. Therefore, Upper Confidence Limit = 941.82+2.026×448.62√38=1089.27Lower Confidence Limit = 941.82−2.026×448.62√38=794.36Thus, it can be said with 95% confidence that the average intake of calcium by women isbetween 794.36 and 1089.27.Part D
