The average low-density lipoprotein (LDL) cholesterol level of adult males is 142 milligrams per deciliter. You want to determine whether the true mean male LDL cholesterol level is higher than the average. You decide to pull a random sample of 10 adult males and measure their LDL cholesterol level. You find the sample mean is 145.3 milligrams per deciliter and the standard deviation is 5.39 milligrams per deciliter. What are the test statistic and the p-value?
a) The test statistic is 3.3 and the p-value is 0.0422.
B)The test statistic is 0.0422 and the p-value is 3.3.
c)The test statistic is 1.94 and the p-value is 0.0424.
D)The test statistic is 0.0422 and the p-value is 1.94.
E) The test statistic is 1.7 and the p-value is 1.94.
Homework Answers
t test statistic formula is
=1.94
P value =0.0424..................by using Excel command =TDIST(1.94,9,1)

The cholesterol levels of adult males are approximately normally distributed with a mean of 224 mg/dl, and a variance, o', of 521. Some researchers claim that the variance of cholesterol levels of adult males is less than 521. A sample of 15 adult males' blood tests had a mean of 222.5 mg/dL and a variance of 192. Is there enough evidence to conclude, at the 0.05 level of significance, that the variance of cholesterol levels of adult males is less...

A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of men aged 20 to 34. Suppose that in fact the LDL cholesterol level of all men aged 20 to 34 follows the Normal distribution with mean μ = 119 milligrams per deciliter (mg/dL) and standard deviation σ = 25 mg/dL. Use Table A for the following questions, where necessary. (a) What is the probability that x takes a value between 116 and 122 mg/dL?...

A researcher aims to test a hypothesis that average LDL cholesterol level is greater among diabetic adults that have HIV in Chicago compared to Chicago diabetic adults who don't have HIV. The average LDL cholesterol level among diabetic patients in Chicago who don't have HIV is 150 mg/dL. She is considering a design with a sample with 150 randomly chosen adult diabetic patients with HIV in chicago and a level of significance at 0.05. She wants to calculate the statistical...

A laboratory claims that the mean sodium level, μ, of a healthy adult is 142 mEq per liter of blood. To test this claim, a random sample of 35 adult patients is evaluated. The mean sodium level for the sample is 137 mEq per liter of blood. It is known that the population standard deviation of adult sodium levels is 12 mEq. Assume that the population is normally distributed. Can we conclude, at the 0.05 level of significance, that the...

The following table contains cholesterol levels collected from
non-smoking males. The before cholesterol level is before they
exercised, and the after cholesterol level was taken after the same
subject regularly exercised for two months. It is claimed that the
mean cholesterol level before exercise is greater than that after
exercise. Assume that the population of cholesterol level
difference (before-after) is normally distributed. Test the claim
at the 0.01 level.

Obesity in adult males is associated with lower levels of sex hormone. A study investigated a possible link between obesity and plasma testosterone concentrations in adolescent males between the ages of 14 and 20 years. Plasma testosterone level is measured in nanomoles per liter of blood (nmol/1) for a sample of 25 obese adolescent males. The sample mean is 0.26 nmol/l, and the sample standard deviation is 0.11 nmol/l a) What distribution does the mean testosterone level in the sample...
