A researcher would like to study the life style of Hong Kong people. In the study, he asked his participants to install a health apps in their smartphone in order to monitor some of their health habits (e.g. no. of hours of sleep per day, no. of steps they walk per day, no. of cigarettes they smoke per day, etc). The following shows a summary of the smoking habit of 100 smokers in the sample: No. of cigarettes smoked per day Relative cumulative Frequency Relative frequency frequency 4 20 12 3e 4P 15 17 60 18e 10 6 4 7 99 10 20 11 2 12 100% a. Which scale of measurement was used to measure the smoking habit of smokers? b. Complete the above frequency distribution table by filling in (i) relative frequency and (ii) relative cumulative frequency c. Draw a frequency polygon of the data (use simple frequency, fas y-axis) d. Based on the frequency polygon drawn in (c), comment on the shape of the distribution. e. Describe the central tendency of the data by computing (i) mean, (ii) median, and (iii) mode. + f. Describe the dispersion of the data by computing (i) variance and (ii) standard deviation. ttttttttttt

Permutations and Combinations

If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.

Counting Theory

The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
