Assume a recent sociological report states that university students drink 5.70 alcoholic drinks per week on average, with a standard deviation of 1.7201. Suppose Jason, a policy manager at a local university, decides to take a random sample of 170 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.

Answer #1

Solution :

Given that ,

mean = = 5.70

standard deviation = = 1.7201

n = 170

mean of the samoling distribution = 5.70

standard deviation of sampling distribution =  / n = 1.7201/ 170=0.13

In a recent study, Lepp, Barkley, and Karpinski (2014) reported that undergraduate students spend an average of 278.67 (standard error of the mean = 9.79) minutes per day using their cell phones. You may wonder whether cell phone usage at your university differs significantly from Lepp, Barkley, and Karpinski’s (2014) findings. Suppose a recent survey of students at your university found that students spend 255 minutes per day using their cell phones. Note that standard error of the mean and...

Recent research has suggested that adolescent drinking behaviors have escalated. Assume national statistics presume that only 14% of adolescents aged 13-17 engage in alcohol consumption. A sample of 58 participants in this age range is collected and 13 participants report consuming alcohol on a regular basis. 1) Calculate the probability of observing the results witnessed in the sample. 2) Determine the mean and standard deviation for the distribution under the assumptions made in part A.

A student group claims that first year students at a university must study 2.5 hours per night during the school week. A skeptic suspect that they study less than that on average. A class survey finds that the average study time claimed by 269 students is 137 minutes. Regard these students as a random sample of all first-year students and suppose we know that study times follow a Normal distribution with standard deviation of 65 minutes. Is there evidence that...

Over the last 20 years, the number of students who hold a job while attending university fulltime has increased. Work responsibilities may ‘compete’ for time and energy with course responsibilities, and consequently, may affect student academic success. An educational researcher is interested in determining whether student employment influences academic success. The research has obtained a relevant sample of university students, and has determined the following information for each student: i. their employment status (specifically, the typical number of hours worked...
