1. QUESTION 2(8 marks in total)
2. These questions are based on the use of special functions you learned about in Lab 2.

• Create a suitable graph to display the age distribution of those participants who are thirty and older (ie. 30 years).
• Create a suitable graph to display the gender distribution of those who are 'Dissatisfied' with their course.
• Create a suitable graph for Height, for only those who are 175cm or less (i.e. 175).
• Create a suitable graph of IQ scores, for those with IQ greater than 100.Should begin at 100
• Obtain one table which shows descriptive statistics separately for those who like memes and those who don't. The table should include mean, median, mode, standard deviation, minimum, maximum, and range.
• Obtain a table with mean, median, and mode for 'time on social media', for those who are 'Very satisfied' with their course.
• Using 'CourseSatisfaction'create a variable 'CourseSatisfaction2' with only two categories (Those who are happy with their course and those who are not happy

with their course):

• Group 1: Happy = (Satisfied + Very satisfied)
• Group 2: Unhappy = (Dissatisfied + Very dissatisfied)
• oNow,obtainonetablethatshowsmean,numberofcases,andstandard deviations for the two groups (ie. Happy & Unhappy) regarding their Alcohol consumption.

Alcohol consumption has been measured as drinks per week. Create a new variable, and then produce a table that shows the average alcohol consumption for males, females, and other gender, per month(if there are four weeks in a month)?
