Q2. (a) During a clinical trial, observed adverse effects of a drug are often classified by the following categories: Mild: Experience was trivial and did not cause any real problem. Moderate: Experience was a problem but did not interfere significantly with patient's daily activities or clinical status. Severe: Experience interfered significantly with the normal daily activities or clinical status. Based on 1110 male and female patients involved in the Phase I trial for Bigomycin, it was observed that 810 experienced no adverse effects, while 216, 72, and 12 subjects suffered from mild, moderate, and severe adverse effects, respectively. The percentage of male and female among the categories of the adverse effects is equal (irrespective of all the categories of observed adverse effects the percentage of male and female is equal). (i) Prepare tabular presentations for this data. (ii) What type of tabulation it is. (b) The breakdown causes of a particular machine in an industry over a period of year are given below where ? is an integer. There are total 900 breakdowns and these are occurred mainly due to three types of causes: electrical, mechanical and misuse. Represent the following data using a pie diagram where ? is an integer
