\nDescription of the assignment and data
\nThe assignment centres around a study of drinking habits of young adults.
\nThe data stored in the Microsoft Excel file named SDM AppliedProject 2021.3.xlsx is to be used for the assignment. It can be downloaded from vUWS.
\nYou are to use the data set assigned to you by your teacher to answer all the questions in this assignment.
\nThe data in this file were gathered from young adults aged between 18-30. The participants were surveyed about their drinking behaviour on the previous weeks, while drinking alone, and while drinking with a romantic partner.
\nThe data set comprises of the following variables:
\nGender Gender of the participants:
\n1=Female
\n2=Male
\nAge Age of the participants, in years
\nAlcohol (Drink Alone) Amount of alcohol consumed (per week) by the participants when drinking alone, in standard drinks
\nAlcohol (Drink with Partner) Amount of alcohol consumed (per week) by the participants when drinking with a romantic partner, in standard drinks
\n(a standard drink is any drink containing 10 grams of alcohol)
\nNOTE: The data was randomly created for the sole purpose of this assignment.<\/p>\n
Question 1 (6 marks) Marks
\nIn this question you are to investigate the distribution of the amount of alcohol consumption when drinking alone by using descriptive statistics, and a visual depiction of your results.<\/p>\n
a) Using RStudio, obtain the following descriptive measures for alcohol consumption when drinking alone. * [2]
\ni) Mean
\nii) Median
\niii) Standard deviation
\niv) Range
\nb) Using RStudio, construct a histogram with 5 classes* [2]
\nYou must clearly label the axes and title the graph. [2]
\nc) Using RStudio, construct a 90% confidence interval for the population mean alcohol consumption when drinking alone*. [2]
\n* Evidence of work in RStudio is required<\/p>\n
Question 2 (8 marks)
\nIt is believed that to reduce the risk of harm from alcohol-related disease or injury, healthy men and women should drink no more than 6 standard drinks a week.
\nIn this question you are to investigate if the average alcohol consumption when drinking alone is within the healthy limit, by carrying out a hypothesis test.<\/p>\n
a) Using RStudio, obtain an output for a hypothesis test at a 5% level of significance to determine if the alcohol consumption when drinking alone is less than 6 standard drinks. (Assume that the amount of alcohol consumption when drinking alone are normally distributed). * [2]<\/p>\n
b) Using the information in the output, conduct a hypothesis test at a 5% level of significance to determine if the alcohol consumption when drinking alone is less than 6 standard drinks:
\ni) State the null and alternative hypothesis [1]
\nii) State the test statistic including the degrees of freedom [1]
\niii) State the decision rule [1]
\niv) State the p-value [1]
\nv) State the decision by giving reasons [1]
\nvi) Write down the conclusion [1]
\n* Evidence of work in RStudio is required<\/p>\n
Question 3 (8 marks)
\nIn this question you are to investigate if there is a significant difference between the alcohol consumption when drinking alone and when drinking with a partner, by carrying out a hypothesis test for the paired difference.
\nMarks
\na) Using RStudio, obtain an output for a hypothesis test at a 10% level of significance. Assume that the paired differences are normally distributed. * [2]<\/p>\n
b) Using the information in the output, conduct a hypothesis test at a 10% level of significance to determine if the alcohol consumption differs significantly when drinking alone and when drinking with a partner:
\ni) State the null and alternative hypothesis [1]
\nii) State the test statistic including the degrees of freedom [1]
\niii) State the decision rule [1]
\niv) State the p-value [1]
\nv) State the decision by giving reasons [1]
\nvi) Write down the conclusion [1]<\/p>\n
* Evidence of work in RStudio is required<\/p>\n
Question 4 (8 marks) Marks
\nIn this question you are to investigate if there is a correlation between the age and the alcohol consumption (when drinking alone), by performing a regression analysis.
\na) Using RStudio, obtain a linear regression output. You must include both the graphical display and statistical analysis summary. * [2]
\nb) By examining the scatter plot discuss if there is a correlation between the age and the alcohol consumption (when drinking alone). [2]
\nc) State the coefficient of determination. [1]
\nd) Obtain the correlation coefficient. [1]
\ne) Discuss the correlation between the age and the alcohol consumption (when drinking alone) by referring to the numerical values obtained in part c) and part d). [2]
\n* Evidence of work in RStudio is required
