Answer 1

Step-by-step explanation:

Given A factory makes tins of tomatoes. On average, a full can should weigh 410 g. A sample of 20 cans is tested. The weights are shown below.

410 410 411 412 408 411 409 414 416 410

410 412 413 415 410 415 409 410 412 411  

• So given sample of 20 cans which is tested. So the weights are given.
• 410 410 411 412 408 411 409 414 416 410
• 410 412 413 415 410 415 409 410 412 411
• Mean = sum of all data / number of data
• We need to find the average or Mean of the above given sample. So we get
• 410 + 410 + 411 + 412 + 408 + 411 + 409 + 414 + 416 + 410
• 410 + 412 + 413 + 415 + 410 + 415 + 409 + 410 + 412 + 411 / 20
• = 8,228 / 20
• = 411.4
• Since the average is not 410 g the canning machine needs to be adjusted.
