Answer:
There are three kind of beta-thalassemia.
Total possible outcome= 3 types of beta- thalassemia + 1 [child will have no trace of disease] = 4
As we know Probability(outcome) =
Probability that the child will have beta-thalassemia major =\frac{_{1}^{3}\textrm{C}}{_{1}^{4}\textrm{C}}
=
∴ favorable=
And , Total =
Probability that the child will have no trace of the disease=

Answer:
(a)
(b) The broker rejects the hypothesis that the mean price is $243,772, when it is the true mean cost.
(c) The broker fails to reject the hypothesis that the mean price is $243,772, when the true mean price is less than $243,772.
Step-by-step explanation:
(a) The null and alternative hypotheses are:
(b) The <em>type I error</em> says that reject the when it is true.
Thus, <em>type I error</em> is: The broker rejects the null hypothesis that the mean price of home is $243,772, when it is the true mean cost.
(c) The <em>type II error</em> says that accept the when it is false.
Thus, <em>type II error</em> is: The broker fails to reject the null hypothesis that the mean price of single-single home is $243,772, when the true mean price is less than $243,772.
