Use the appropriate attributes! b. Assign the label value of 0=female and 1=male for sex variable. c. Create the new variable called “BMI” from weight and height of students. Use the formula of 𝐵𝑀𝐼 = ௐ௘௜௚௛ ு௘௜௚௛ d. Use Age variable, and then categorize it into “agecat” with values of 0 for <21 years, 1 for 22-25 years and 2 for >26 years’ students. e. Use sex variable, and then recode in to sex1 variable with values of 8888 for female and 999 for male. f. Without delating any data, select the data for female students only! 2. Use the demo.sav data set, then  Write the process/menu’s you followed to get the output, before displaying it,  Check the assumptions, where they needed, and  Write the brief description or interpretation for your outputs a. Compute and summarize the N, minimum, maximum, and mean for age, income and car variable b. What is the mean age for female groups? c. How many numbers of males are highly satisfied to their job? d. Create at least one using e. For variables like, Age in years (age), marital status (marital), house old income (income), price of primary vehicle (car) and level of education (ed) create at least one appropriate chart/graph from pie chart, histogram, simple, clustered and stacked bar chart. Please add the appropriate title, size, axis name, colors and footnote for all created charts. f. Use the same variables in (d) and compute the mean, median, and mode for the appropriate variables. g. For Age in years (age) and house old income (income) variables, compute the skewness and kurtosis, then summarize the result. h. Use variables listed in (d), and construct the frequency table for the nominal and ordinal variables. 3. Use “Employee” data set from SPSS samples, then  Identify the appropriate test for the claim  Write the possible null and alternative hypothesis,  Write all menus you followed to get the output,  Give the decision for your hypothesis test, and  Write the valid and clear interpretation for your output for the following questions. a. At 5% level of significant, is there enough evidence to say that the mean beginning salary of custodial is less than $30,000. b. Is there a significant difference between clerical and custodial job category on employees current salary? c. Is there a statistically significant difference between beginning salaries and current salaries of custodial? d. Assume the population variances among groups are constant, and the samples are from normality distribution, and then test the claim that there is no significant difference in job categories of employment (managerial, clerical and custodial) on their salary change. If there, which group(s) that is (are) significantly different? (Use salary change = current salary - beginning salary). Yasaralgn kachalk leh zare
