- the mean and standard deviation of hemoglobin level of 23 vagrant students and 21 school children were found to be 10 g/dl, 2.2g/dl and 14g/dl, 2.9g/dl respectively. Is there statistically significant difference with the average hemoglobin of the two groups?The mean and standard deviation of hemoglobin level of 23 vibrant students and 21 school children were found to be 10g/dl,2.2g/dl and 14g/dl, 2.2g/dl respectively.is there statistically significant difference with the average hemoglobin of the two groups?A survey recently reported that the mean national annual expenditure for inpatient andoutpatient services of all persons over 64 years of age was $5,423 with a standarddeviation of $979. A random sample of 352 persons over age 64 living in Sudbury had anaverage expense of $5,516. We want to test whether the mean inpatient and outpatient expense of all Sudbury residents over age 64 is higher than the national average of $5,423. Calculate the P-value for this test.
