kiruha [24]

About 296 households have more than three children. Then the correct option is C.

<h3>How to find that a given condition can be modeled by binomial distribution?</h3>

Suppose we have random variable X pertaining to a binomial distribution with parameters n and p, then it is written as

 

The expected value will be

E(X) = np

Carmen used a random number generator to simulate a survey of how many children live in the households in her town.

There are 1,346 unique addresses in her town with numbers ranging from zero to five children.

The results of 50 randomly generated households are shown below.

Children in 50 Households

Number of Children        Number of Households

             0                                          5

             1                                          11

             2                                        13

             3                                        10

             4                                         9

             5                                         2

Then the value of p and n will be

p = 11/50

n = 1346

Then the expected value will be

E(x) = (11/50) x 1346

E(x) = 296.12 ≈ 296

Then the correct option is C.

A teacher gave a test with 50 questions, each worth the same number of points. Donovan got 39 out of 50 questions right. Maci's
amm1812

39/50= 0.78 times 100= 78

78 is Donovan's score

if maci's score is 10 percentage points higher

78+10=88

x /50 =0.88 times 100= 88

x=44

each question is 2 points:  88-78= 10/2=5

Maci answered 5 questions correctly.
