The average triglyceride level of adult males is 126 milligrams per deciliter. You want to determine whether the true mean male
triglyceride level is more than the average. You decide to pull a random sample of eight adult males and measure their triglyceride level. You find the sample mean is 127.9 milligrams per deciliter and the standard deviation is 4.12 milligrams per deciliter. What are the test statistic and the p-value?
1 answer:
Answer: The test statistic is 1.30 and the p-value is 0.1167.
Step-by-step explanation:
A test statistic is a random variable which is calculated from sample data and also used in a hypothesis test. It can also be used to know whether to reject the null hypothesis.

Find out the what is the percent error in the measurement, to the nearest tenth of a percent .
To prove
Formula
Where error = | Approx - Exact |
As given
Karen measures the width of a garden plot and records that it is 44.25 meters. Its actual width is 45.5 meters.
Approx value = 44.25 meters
Actual value = 45.5 meters
error = | 44.25 - 45.5 |
= |-1.25|
= 1.25
Put in the formula
Percentage error = 2.7%
Therefore the percentage error is 2.7% .

Step-by-step explanation:
We have a sum of money ($6000) compounded daily at an annual interest rate of 8.5% for 6 years.
If the interest is compound daily, and we take a m=365 days a year (or 365 subperiods m), the daily nominal interest rate is:
Then, we can express the final valueo of $6000 compounded daily at an annual interest rate of 8.5% for 6 years as:
