Question

Aortic stenosis refers to a narrowing of the aortic valve in the heart. An article gave the following data on aortic root diameter (cm) and gender for a sample of patients having various degrees of aortic stenosis. M: 3.9 3.2 3.9 4.2 4.1 4.0 3.2 3.8 2.9 4.2 3.2 4.0 3.3 F: 3.9 2.4 3.0 2.8 4.4 4.5 2.9 2.9 3.0 2.8 (a) Compare and contrast the diameter observations for the two genders. (Round your answers to two decimal places.) Aortic root diameters for males have mean cm, median cm, standard deviation cm, and fourth spread cm. The corresponding values for females are x? = cm, x? = cm, s = cm, and fs = cm. Aortic root diameters are typically (though not universally) somewhat ---Select--- for females than for males, and females show ---Select--- variability. The distribution for males is ---Select--- skewed, while the distribution for females is ---Select--- skewed. (b) Calculate a 10% trimmed mean for each of the two samples. (For the male sample, the interpolation method mentioned in Section 1.3 must be used). (Round your answers to two decimal places.) 10% trimmed mean for females cm 10% trimmed mean for males cm Compare to other measures of center.
