Answer:
(D) 4
Step-by-step explanation:
The graph which is a pie chart is produced and attached below.
There are a total of 80 Students.
From the graph, 25% choose Target and 20% choose Ross as their favorite store.
- 25% of 80 =0.25 x 80=20
- 20% of 80 =0.2 x 80=16
Number of Students who choose Target as their favorite store over Ross
=20-16
=4 Students.

Answer:
The Normal distribution is a continuous probability distribution with possible values all the reals. Some properties of this distribution are:
Is symmetrical and bell shaped no matter the parameters used. Usually if X is a random variable normally distributed we write this like that:
The two parameters are:
who represent the mean and is on the center of the distribution
who represent the standard deviation
One particular case is the normal standard distribution denoted by:
Example: Usually this distribution is used to model almost all the practical things in the life one of the examples is when we can model the scores of a test. Usually the distribution for this variable is normally distributed and we can find quantiles and probabilities associated
