Question

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 415415 gram setting. Based on a 2424 bag sample where the mean is 409409 grams and the variance is 784784, is there sufficient evidence at the 0.10.1 level that the bags are underfilled? Assume the population distribution is approximately normal.

Step 1 of 5:

State the null and alternative hypotheses.

Step 3 of 5:

Specify if the test is one-tailed or two-tailed.

Step 4 of 5:

Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.

Step 5 of 5:

Make the decision to reject or fail to reject the null hypothesis.

Answer #1

A manufacturer of banana chips would like to know whether its
bag filling machine works correctly at the 446 gram setting. Based
on a 26 bag sample where the mean is 450 grams and the variance is
900, is there sufficient evidence at the 0.01 level that the bags
are overfilled? Assume the population distribution is approximately
normal.
Step 1 of 5 : State the null and alternative hypotheses.

A manufacturer of banana chips would like to know whether its
bag filling machine works correctly at the 402.0 gram setting. It
is believed that the machine is underfilling the bags. A 45 bag
sample had a mean of 392.0 grams. A level of significance of 0.1
will be used. Is there sufficient evidence to support the claim
that the bags are underfilled? Assume the standard deviation is
known to be 29.0.
What is the conclusion?
a) There is not...

underfilled?

A manufacturer of banana chips would like to know whether its
bag filling machine works correctly at the 404404 gram setting. Is
there sufficient evidence at the 0.010.01 level that the bags are
underfilled? Based on a 3030 bag sample, the manufacturer fails to
reject the null hypothesis.
What is the conclusion?
. There is sufficient evidence at the 0.010.01 level of
significance that the machine is underfilling the bags.
. There is not sufficient evidence at the 0.010.01 level...
