What conclusion would you make at the « = 0.01 significance level? Because the P-value of 0.0806 > a = 0.01, we reject Ho. We do not have convincing evidence that the true mean weight for all loas of bread produced at the bakery is less than one pound. Because the P-value of 0.0806 > a = 0.01, we fail to reject Ho. We do not have convincing evidence that the true mean weight for all loaves of bread produced at the bakery is less than one pound. Because the P-value of 0.0806 > a = 0.01, we reject Ho. We have convincing evidence that the true mean weight for all loaves of bread produced at the bakery is less than one pound. O Because the P-value of 0.0806 > x = 0.01, we accept Ho. We have convincing evidence that the true mean weight for all loaves of bread produced at the bakery is one pound. Because the P-value of 0.0806 > a = 0.01, we fail to reject Ho. We have convincing evidence that the true mean weight for all loaves of bread produced at the bakery is less than one pound.

Question
Transcribed Image Text:The mean weight of loaves of bread produced at the bakery where you work is supposed to be 1 pound. You are the
supervisor of quality control at the bakery, and you are concerned that new employees are producing loaves that are too
light. Suppose you weigh an SRS of bread loaves and find that the mean weight is 0.975 pound.
We want to test
Ho = 1
H < 1
where i = the true mean weight (in pounds) of bread loaves produced at the bakery.
The P-value for the test is 0.0806.
What conclusion would you make at the a = 0.01 significance level?
Because the P-value of 0.0806 > a = 0.01, we reject Ho. We do not have convincing evidence that the true mean
weight for all loazs of bread produced at the bakery is less than one pound.
Because the P-value of 0.0806 > a = 0.01, we fail to reject Ho. We do not have convincing evidence that the true
mean weight for all loaves of bread produced at the bakery is less than one pound,
Because the P-value of 0.0806 > a = 0.01, we reject Ho. We have convincing evidence that the true mean weight
for all loaves of bread produced at the bakery is less than one pound.
O Because the P-value of 0.0806 > x = 0.01, we accept Ho. We have convincing evidence that the true mean weight
for all loaves of bread produced at the bakery is one pound.
O Because the P-value of 0.0806 > & = 0.01, we fail to reject Ho. We have convincing evidence that the true mean
weight for al1 loaves of bread produced at the bakery is less than one pound.

Expert Solution
Step 1
If the p-value is less than the level of significance, the null hypothesis is rejected. Because the p-value in this case (0.0806) is greater than the level of significance (0.01), the null hypothesis is not rejected. Therefore, it can be concluded that there is insufficient evidence to conclude that the true mean is less than 1.
