Question

KNOWN VARIANCES or LARGE SAMPLE
CASE
Example:
A survey of practicing certified public accountants on attitudes to women in the
profession was carried out. Survey respondents were asked to react on a scale
from one (strongly disagree) to five (strongly agree) to the statement: 'Women in
public accounting are given the same job assignments as men'. For a sample of
186 male accountants, the mean response was 4.059 and the sample standard
deviation was 0.839. For an independent random sample of 172 female
accountants, the mean response was 3.680 and the sample standard deviation
was 0.966. Test the null hypothesis (a = 0. 1%) that the two population means are
equal against the alternative that the true mean is different for male accountants.
