An agricuicure publication daims that the population mean of the birth weights for all Alpine goats is 2.33 kg. A veterinary service has hired you to test that daim. To do so, you select a random sample of 35 Alpine goats and record the birth weights. Assume it is known that the population standard deviation of the birth weights of Alpine goats is 1.36 kg. Based on your sample, follow the steps below to construct a 95% confidence interval for the population mean of the birth weights for all Alpine goats. Then state whether the confidence interval you construct contradicts the publication's daim. (If necessary, consult a list of formulas.)

Question
An agricuiture publication daims that the population mean of the birth weights for all Alpine goats is 2.33 kg. A veterinary service has hired you to test that
claim. To do so, you select a random sample of 35 Alpine goats and record the birth weights. Assume it is known that the population standard deviation of the
birth weights of Alpine goats is 1.36 kg.
Based on your sample, follow the steps below to construct a 95% confidence interval for the population mean of the birth weights for all Alpine goats. Then
state whether the confidence interval you construct contradicts the publication's claim. (If necessary, consult a list of formulas.)
(a)
Click on "Take Sample" to see the results from your random sample of 35 Alpine goats.

Enter the values of the sample size, the point estimate for the population mean, the population standard deviation, and the critical value you need for your
95% confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute".

(b)
Based on your sample, graph the 95% confidence interval for the population mean of the birth weights for all Alpine goats.
· Enter the lower and upper limits on the graph to show your confidence interval.
• For the point (), enter the publication's daim of 2.33 kg.
95% confidence interval:
0.00
10.00
2.33

(c)
Does the 95% confidence interval you constructed contradict the publication's claim? Choose the best answer from the choices below.
O No, the confidence interval does not contradict the claim. The publication's claim of 2.33 kg is inside the 95% confidence
interval.
O No, the confidence interval does not contradict the claim. The publication's claim of 2.33 kg is outside the 95%
confidence interval.
O Yes, the confidence interval contradicts the claim. The publication's claim of 2.33 kg is inside the 95% confidence
interval.
O Yes, the confidence interval contradicts the claim. The publication's claim of 2.33 kg is outside the 95% confidence
interval.
