Question
(a) (b) The number of fire calls in a day at a fire department is recorded for 100 randomly selected days. The data is summarized as below: (i) (ii) Number of calls 0 1 2 3 4 5 6 Total Number of days 15 20 17 21 9 10 8 100 What is a reasonable probability model for this data? Test if this model adequately describes the data. Use a = 0.01. An experiment is designed to study the side effects of two drugs used as treatments for a certain ailment. A group of 180 subjects are randomly assigned to three groups. After the specified drug is given, the side effects are recorded. Side Effects None Minor Major Total ΣΣΥ = 5,000 Drug A Drug B 40 36 16 16 4 60 8 60 Placebo 30 24 6 60 Total 106 56 18 180 Is there evidence of a difference among the drugs? Test at the 0.10 level of significance.
