Statistics and SPSS Analysis, R Frequently Asked Questions
1.Consider the comparision of serum iron levels in healthy children and children suffering from cystic fibrosis.One sample was drawn from the population of healthy children and the other was drawn from the population of children suffering from cystic fibrosis. n1=10, x1=19.0μmol/L,s1=6.0μmol/L, n2=15, x2=11.7μmol/L and s2=6.4μmol/L. please judge whether the population means of healthy children and children suffering from cystic fibrosis are equal or not? Write down the right hypothesis test and procedures.(α=0.05，
i need help in this question?
A two-sample t-test can be used here. Perhaps x1 and x2 are means of both groups. If so then calculated the value of t-test will be 2.86.
$t=frac{overline{x}_1 – overline{x}_2} { sqrt{sp^2 left(frac{1}{n_1}+ frac{1}{n_2} right) } }$
$=frac{19-11.7} {sqrt{39.019left(frac{1}{10}+frac{1}{15} right) }} = 2.86$
where $sp^2 = frac{(n_1-1)*s_1^2 + (n_2-1)*s_2^2}{n_1-n_2-2} = 39.019$
We need a table value at the significance level of 0.05 and 23 degrees of freedom, which is, in this case, is 1.7138 (one tail) or 2.0686 (two tail). Since computed value is greater than either one tail table value or two tail table value we will say that the population means of healthy children and children suffering from cystic fibrosis are not equal.
