1A)
Let x represent the hemoglobin count (HC) in
grams per 100 milliliters of whole blood. The distribution for HC
is approximately normal with ? = 14 for healthy adult women.
Suppose that a female patient has taken 12 laboratory blood samples
in the last year. The HC data sent to her doctor is listed below.
We would like to know if the data indicates this patient has
significantly high HC compared to the population.
22,19,14,19,15,16,21,22,21,14,20,20
Give the p-value and interpret the results.
a) p = .0562; Based on 5%
significance level, I will fail to reject the null hypothesis and
conclude this patient does not have a high HC level.
b) p = 0.0001; Based on 5%
significance level, I will reject the null hypothesis and conclude
this patient has a high HC level.
c) p = 0.0001; Based on 5%
significance level, I will fail to reject the null hypothesis and
conclude this patient does not have a high HC level.
d) p = .1053; Based on 5%
significance level, I will fail to reject the null hypothesis and
conclude this patient does not have a high HC level.
e) p = 0.0003; Based on 5%
significance level, I will reject the null hypothesis and conclude
this patient has a high HC level.
1B) In a test of significance, assuming the null hypothesis is
true, the probability of observing the test statistic extreme or
more extreme than the observed test statistic (in the way of the
alternative hypothesis) is
a) the probability the null hypothesis is
true.
b) the probability the null hypothesis is
false.
c) the p-value.
d) the level of significance ?.
e) None of the above
