Assume a recent sociological report states that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101. suppose jason, a policy manager at a local university, decides to take a random sample of 125 university students to survey them about their drinking habits. determine the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption. provide your answer with precision to two decimal places. mean of sampling distribution = standard deviation of sampling distribution =

The mean of the sampling distribution of the sample mean alcohol consumption is 4.10 alcoholic drinks per week on average.

The standard deviation of the sampling distribution of the sample mean alcohol consumption is 0.17.

Step-by-step explanation:

We have these following informations:

Assume a recent sociological report states that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101.

Determine the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption.

The mean of the sampling distribution of the sample mean is the same of that university students. So the mean of the sampling distribution of the sample mean alcohol consumption is 4.10 alcoholic drinks per week on average.

The standard deviation of the sampling distribution of the sample mean alcohol consumption is the division of the standard deviation of the sample mean divided by the length of the sample. So

The standard deviation of the sampling distribution of the sample mean alcohol consumption is 0.17.

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
