A light bulb factory produces 1,188 light bulbs every hour. Approximately 3.83% of the light bulbs are defective, and do not work. Using the binomial distribution, what is the standard deviation of the number of defective bulbs produced in an hour

The standard deviation of the number of defective bulbs produced in an hour is 6.615

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

The standard deviation of the binomial distribution is:

In this problem, we have that:

What is the standard deviation of the number of defective bulbs produced in an hour

The standard deviation of the number of defective bulbs produced in an hour is 6.615

answer: i cant see the picture

step-by-step explanation:

can u take a better picture

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
