Tylenol needs to make sure that the standard deviation for the amount of acetaminophen in its regular strength tablet must be less than 5 mg. To test this, the quality control manager randomly selects 20 pills and found that the standard deviation amount of acetaminophen was 3.89 mg. Test the claim at the a=0.10 level of significance. Note: The data is normal with no outliers. Write your answer in the following form Test Statistic, Critical Value, Conclusion Example: 15.247, 13.848, There is not sufficient evidence that the standard deviation is more than 7.

This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability. All work must be shown in order to receive any credit. Please upload your completed assignment here. The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard deviation of 0.25 hours. A sample size of n = 60 is drawn randomly from the population. Find the probability that the sample mean is between two hours and three hours.
Consider a set of data in which the sample mean is 30.230.2 and the sample standard deviation is 7.87.8. Calculate the z-score given that x=31.4x=31.4. Round your answer to two decimal places.
AARP reported that the average senior citizens living at high altitudes claim their systolic blood pressure is lower than the average of 160. To test this claim, 16 senior citizens living at high altitudes were selected at random and their blood pressures checked. Their mean systolic pressure was 151, the standard deviation for the sample was 12. Do senior citizens living at high altitudes have significantly lower systolic blood pressure? Use the 0.05 level of significance.Remember to show your steps (including all relevant information) and explicitly verify that all assumptions of the procedure are satisfied. show the steps on how to solve it
Assume that the test scores for biostatistics midterm examination are normally distributed with a mean of 74 and a standard deviation of 10. i. Suppose that you receive a score of 88.

The average cost of tuition, room and board at small private liberal arts colleges is reported to be $8,500 per term, but a financial administrator believes that the average cost is higher. A study conducted using 350 small liberal arts colleges showed that the average cost per term is $8,745 with a standard deviation of $1,200. Let = 0.05., what is our decision about the average cost? Select one: a.Less than $8,500 b.Greater than 8500 c.None is correct d.Not equal to $8,500 e.Equal to $8,500
The mean weights for medium navel oranges is 9.8 ounces. Suppose that the standard deviation for the oranges is 3.3 ounces. Which would be more likely, an orange weighing 14 ounces or an orange weighing 4.9 ounces? Explain. Choose the best answer below: A. A 4.9 ounce orange is more likely (z = 1.48) compared with an orange weighing 14 ounces (z = 4.24). B. A 4.9 ounce orange is more likely (z = -1.48) compared with an orange weighing 14 ounces (z = 1.27). C. A 14 ounce orange is more likely (z = -1.48) compared with an orange weighing 4.9 ounces (z = 1.27). D. A 4.9 ounce orange is more likely (z = 1.27) compared with an orange weighing 14 ounces (z = -1.48). E. A 14 ounce orange is more likely (z = 1.27) compared with an orange weighing 4.9 ounces (z = -1.48).
