Calculate the monthly cost of replacing diodes based on failure probability and determine if a student can buy a gown based on expected money.

Question

i. The laptops that are purchased by a company have 742 diodes with a life span of five months. These diodes fail on a regular basis according to the following probability distribution:

Life (months)	1	2	3	4	5
Probability of failure	0.10	0.30	0.35	0.20	0.05

If the cost of replacing a diode is ₦100, calculate the monthly cost of replacing the diodes as they fail. (4 Marks)

ii. Tadet, a student in the Accountancy Department of a Polytechnic, has the following chances of receiving money from her relatives:

45% chance of receiving ₦5,000 from her sister,
33% chance of receiving ₦8,000 from her brother,
16% chance of receiving ₦11,000 from her aunt,
6% chance of receiving ₦15,000 from her uncle.

Determine if Tadet will be able to buy a gown worth ₦8,000 from the money she is expecting from her relatives. (6 Marks)

QTB – May 2017 – L1 – SA – Q11 – Data Collection and Analysis

This question calculates the first quartile age from an age distribution table of artisans.

Question

If the age distribution of the artisans in a tobacco company is tabulated as follows:

Artisan’s age (years)	Number of Artisans
20 and under 25	3
25 and under 30	14
30 and under 35	18
35 and under 40	11
40 and under 45	3
45 and under 50	1

Then the first quartile age is:
A. 28.38 years
B. 28.39 years
C. 28.93 years
D. 29.38 years
E. 29.93 years
