The correlation analysis assumes that the measurements have a bivariate normal distribution in the population. Select all of the

RoseWind [281]

Answer:

A. True

B. True

C. False

D. False

E. False

F. False

G. True

Step-by-step explanation:

Select all of the features that define a bivariate normal distribution.

(this means that we select only those that are properties of the bivariate normal distribution)

A. Bell-shaped probability distribution in two dimensions rather than one

TRUE because any combination of the two is still normal Z(x,y)=aX+bY

B. A relationship between X and Y that is not linear

TRUE The contours of the distribution are ellipses.

C. The presence of outliers

FALSE possible, but not always.

D. Either X or Y has a decidedly skewed distribution

FALSE normal distributions are symmetric

E. A relationship between X and Y that is linear

FALSE see answer to B

F. A cloud of points that is funnel shaped (wider at one end than the other)

FALSE normal distributions are symmetric

G. The frequency distributions of X andY separately are normal

TRUE For example, in Z(x,y)=aX+bY, putting a or b=0 means that X and Y separately are normal.

djyliett [7]

Answer:

Option A:

Number of seats

Step-by-step explanation:

A discrete quantitative variable is a variable that can be enumerated. This means that they are in units in which numbers can be assigned to and can be counted.

The number of seats present in the car can be counted. This feature can also be evaluated based on its numeral value, rather than its quality. In a simple form, the buyers feel that the more the number of seats present in the car, the more people it can carry. Hence, the family would love to buy a car with a good number of seats in it.

The other features in the options are rather continuous, qualitative, or boolean. Some of them are continuous because they cannot be counted e.g fuel efficiency. The others such as the presence of a sunroof can be seen as a boolean variable. (it can either be true or false)

Type of the transmission is a qualitative variable
