Answer:

If I read your problem write:  126

Step-by-step explanation:

if I interpret this as

- (-3)* 2 * (5) * 2 * (7) * 3  divided by 5 * 2

we can get  126

because:

- (-3)* 2 * (5) * 2 * (7) * 3  divided by 5 * 2

= 6 * 5 * 2 *7 * 3 / (5*2)

= 60*7 * 3/ (5*2)

= 420 * 3 / 10

= 1260/10

= 126

A random sample of n people selected from a large population will be asked whether they have read a novel in the past year. Let
kozerog [31]

Answer:

b. A binomial variable with 25 independent trials

Step-by-step explanation:

The conducted experiment is binomial experiment because outcome can be divided into success or failure. The success would be the people who read novel in the past year and also responses are independent of each other. We have to find the number of trials n in the given problem.

we are given that variance of R=6 and p=probability of success=0.4.

We know that variance of binomial distribution is

Variance=npq

where q=1-p=1-0.4=0.6.

By putting the values in variance formula, we can get the value of n.

6=n*0.4*0.6

6=0.24*n

n=6/0.24

n=25

Hence, random variable R is a binomial variable with 25 independent trials.
