Supposed a study using a random sample of postgraduate students in Sydney found that the average amount of time spent using a mobile phone per day is 5.5 hours. Indicate whether the quantity described above is a population parameter or a sample statistic, and write down the notation. Hints: You may type in how you read the notation, instead of using the symbol itself. E,g. you can write "mu" or "xbar" or "phat" or "rho" or "sigma" for the Greek alphabet or special symbol.

The Sydney Airport Commission set a performance target of 26 minutes for the time taken for passengers to claim their luggage at domestic terminals. In order to monitor performance a study was conducted by taking a random sample of 200 passengers disembarking from Sydney airport.
