d) Suppose this is a representative sample of births in a given year at Johns Hopkins. Suppose,
instead of a sample of seven values, we have a sample of 100 birth weights. How should the mean,
median, and standard deviation of this sample compare to the same statistics for the sample of
seven birth weights?
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.
