A quality control engineer at a potato chip company tests the bag filling machine by weighing bags of potato chips. Not every bag contains exactly the same weight. But if more than 16% of bags are over-filled then they stop production to fix the machine. They define over-filled to be more than 1 ounce above the weight on the package. The engineer weighs 94 bags and finds that 16 of them are over-filled. He plans to test the hypotheses H 0 : p = 0.11 versus H a : p > 0.11. What is the test statistic?

The test statistic is z = 1.865.

Step-by-step explanation:

The test statistic is:

In which X is the sample mean, is the value tested at the null hypothesis, is the standard deviation and n is the size of the sample.

H0: p = 0.11

This means that 0.11 is tested at the null hypothesis, and so:

The engineer weighs 94 bags and finds that 16 of them are over-filled.

This means that:

What is the test statistic?

The test statistic is z = 1.865.

the correct answer is the second option

if you need just tell me and i will come to the rescue.
