(a) Can the consultant conclude at the 5% significance level that the
husband’s mean estimate for the family clothing expenditure is higher than 310
(b) Assume that the true population mean of the husband’s estimate is
315 (dollars) and the true population standard deviation is 34 (dollars).
Calculate the probability of type II error of the hypothesis test
H0: μh = 310
HA: μh > 310
with a 5% significance level.
(c) Can the consultant conclude at the 5% significance level that the
majority (more than half) of wives believe that the family clothing expenditure
is not less than 320 (dollars)?
(d) Can the consultant conclude at the 5% significance level that the
husband’s mean estimate is higher than the wife’s mean estimate? (Hint: you
firstly have to decide the two samples are independent or paired.)
(e) Calculate 95% confidence interval for the population mean difference
between the husband’s estimate and wife’s estimate, and briefly describe what
the confidence interval tells you.
