Assume a recent sociological report states that university students drink 4.14 alcoholic drinks per week on average, with a standard deviation of 1.5301. Suppose Jason, a policy manager at a local university, decides to take a random sample of 150 university students to survey them about their drinking habits.
Determine the mean of the sampling distribution of the sample mean alcohol consumption. Provide your answer with precision to two decimal places
The mean of the sampling distribution of the sample mean alcohol consumption can be calculated using the formula:
μx̄ = μ = 4.14
This means that the mean of the sampling distribution of the sample mean alcohol consumption is equal to the population mean of 4.14 drinks per week.
Therefore, the mean of the sampling distribution of the sample mean alcohol consumption is 4.14, with precision to two decimal places.
To determine the mean of the sampling distribution of the sample mean alcohol consumption, we can use the formula:
Sampling distribution mean = Population mean
In this case, the population mean is given as 4.14 alcoholic drinks per week.
Therefore, the mean of the sampling distribution of the sample mean alcohol consumption is also 4.14.
