1 answer:
Using proportions, it is found that each person consumes 3.57 times as many rice in Brazil and they do in the United States.
<h3>What is a proportion?</h3>A proportion is a fraction of a total amount.
In this problem, we have that:
- The rate in Brazil is of
.
- The rate in the United States is of
.
Hence, the rate between the consumption in Brazil and in the United States is given by:

Step-by-step explanation:
Let <em>X</em> denote the number of women who consider themselves fans of professional baseball.
The proportion of women who consider themselves fans of professional baseball is, <em>p</em> = 0.37.
A random sample of <em>n</em> = 6 women are selected and each was asked if she considers herself a fan of professional baseball.
Each woman's reply is independent of the others.
The random variable <em>X</em> thus follows a binomial distribution with parameters <em>n</em> = 6 and <em>p</em> = 0.37.
(a)
Compute the mean of the binomial distribution as follows:
(b)
Compute the variance of the binomial distribution as follows:
(c)
Compute the standard deviation of the binomial distribution as follows:
