Lactose intolerance is a disorder caused from the inability to digest the sugar lactose. It is not an allergy to milk, but rather is due to the lack of a functional enzyme known as lactase. It is a dominant genetic disorder. A couple, both of whom are lactose intolerant, have two children who have no problem digesting milk or milk products. What are the chances that a third child will be lactose intolerant?

The relationship between weight (in kilograms) and gender was estimated as below in a linear format.
(Male was coded as 0 and Female was coded as 1.)
Weight = -10.23 * Female + 66.73
(The p-value for the coefficient of Female is 0.03.)
Base on the above equation, which of the following statements are true? (Select all that apply. There can be more than one answer.)
Answer options:
In the sample used to estimate the equation, the average weight of females is 66.23 kilograms
In the sample used to estimate the equation, the average weight of females is 56.5 kilograms
In the sample used to estimate the equation, the average weight of males is 66.73 kilograms
Females are expected to weigh 10.23 kilograms less than males
