"You can download the data in an Excel file named "AssignmentDoto-BF1047520.is" from Assignment folder in the MMLS The list below explains the description of the related variables in the Excel sheets. Forable Apa Age of the person in years Smoking Habit The smoking status of the parson!

For each the folowing variables in Table 1. ponerate the output of Buccipower Storiaies using Excel functions. [& marks] Variable weight 10 score Serum cholesterol b. Briefly describe what the statistics reveal about the characteristics (variables in Table 1) of the residents in Klang Valley, Kuala Lumpur. (12marka] The statistics should include the mean, median, standard deviation and the slowmass for each of the variablest.Question 2 125 Marks] a. Construct the 95 percent confidence intervals of the population mean of IQ scores for both male and female residents of Klang Valley. Is the mean of the population IQ scores falls within the confidence interval? Explain. [15 marks] Consider the following information: " Use data in Spreadsheet (Question 20) to compute the sample mean and its standard deviation. Given that the population means are = 118 and #=116. b. Compare the proportion of men who are smokers with proportion of women who are smokers.
