a) A company wishes to review its distribution operation and from its time sheet records it found that 144 vehicles were loaded in a 24 hour period. A frequency distribution table was prepared from the data as follows:

Time to load (minutes) Number of vehicles 40 up to 50 17 50 up to 60 61 60 up to 70 59 70 up to 80 7

From the above data construct :
i) a frequency histogram.
ii) a frequency polygon.
iii) a cumulative frequency curve (ogive).
iv) From your ogive estimate:

- the median loading time
- the interquatile range and quartile deviation.
- The number of vehicles loaded in under 52 minutes.

Question 2

The frequency distribution shows the times taken by 30 pupils to do their Mathematics homework. Times have been measured to the nearest minute.

Time (min) Frequency

14. 4
24. 8
34. 10
35-44 8

i) Construct a histogram of the data.
ii) Construct a polygon.
iii) Construct a less than cumulative frequency table and draw the corresponding curve. Use your curve to estimate: - the median,
- the lower and upper quartile ages, inter quartile range and quartile deviation. - the percentage of pupil spending more than 30 minutes to do their homework

Question 3

On a certain day, 500 cars were park in the parking lots of a shopping complex. The parking duration of each car (to the nearest minute) is shown in the table below.

...in their means and in their standard deviations. Figure 1 shows three normal distributions. The green (left-most) distribution has a mean of -3 and a standard deviation of 0.5, the distribution in red (the middle distribution) has a mean of 0 and a standard deviation of 1, and the distribution in black (right-most) has a mean of 2 and a standard deviation of 3. These as well as all other normal distributions are symmetric with relatively more values at the center...

Q1. What is the link between audit risk and engagement risk? How does the audit risk model allow the auditor to deal with these risks in the most cost effective manner?
Audit risk is the risk that the auditor gives the wrong opinion – this can either be stating errors when there are none or when there are errors stating that there are none. This risk cannot be eliminated as auditors can only provide a reasonable assurance and not absolute,...
