Question

A sample of 184 light bulbs contained 6 defective bulbs, at this rate ,how many defective bulbs would you expect to find in a sample of 1288 light bulbs

Answer 1

To find the number of defective bulbs in a sample of 1288 light bulbs, you can use the proportion of defective bulbs from the given sample.

Step-by-step explanation:

To find the number of defective bulbs that would be expected in a sample of 1288 light bulbs, we can use the proportion of defective bulbs from the given sample.

Proportion of defective bulbs = (number of defective bulbs / total number of bulbs)

So, in the given sample of 184 light bulbs, there are 6 defective bulbs. Therefore, the proportion of defective bulbs is:

Proportion of defective bulbs = 6 / 184

Now, we can use this proportion to find the expected number of defective bulbs in a sample of 1288 light bulbs:

Expected number of defective bulbs = (proportion of defective bulbs) * (total number of bulbs)

Expected number of defective bulbs = (6 / 184) * 1288

Therefore, the expected number of defective bulbs in a sample of 1288 light bulbs is approximately 41.91.

Answer 2

184 x 7 = 1288
7 x 6 = 42
so you have 42 defective bulbs
