Printing for a group?
The batch download puts all 2 tiers' July 2003 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in July 2003
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st July 2003For the ordered data 6, 9, 11, 14, 16, 18, 20, 23, 25, 28, find the interquartile range.
- 2nd July 2003A pictogram key shows 1 symbol = 6 cakes. A row has 1 symbol and a third of a symbol. How many cakes does the row represent?
- 3rd July 2003A spinner with sections A, B and C is spun alongside a fair coin. How many outcomes are in the sample space, and what is P(getting C and Heads)?
- 4th July 2003A class interval is 20-30 with frequency 8. Give the coordinates of the point plotted for this class.
- 5th July 2003A time series shows sales peaking every December for five years in a row. What is this repeating pattern called?
- 6th July 2003Express a risk of 1/20 as a percentage.
- 7th July 2003A box has 4 chocolate and 6 plain biscuits. One biscuit is eaten (it was chocolate), then a second is taken at random. Find P(second is chocolate given first was chocolate).
- 8th July 2003A pictogram uses one whole apple symbol to represent 10 apples sold, but one row shows a half apple symbol with no key given for partial symbols. Why could this be misleading?
- 9th July 2003Find the midpoint of the class interval 10-20.
- 10th July 2003A survey question offers the response options 'Never, Sometimes, Always'. State one improvement that could be made.
- 11th July 2003Find the 3-point moving average of 10, 14, 18.
- 12th July 2003A bag has only red, blue and green counters. P(red) = 0.5 and P(blue) = 0.2. Find P(green).
- 13th July 2003A histogram has bars of equal width. True or false: the height of each bar represents the frequency for that class.
- 14th July 2003A box plot shows minimum 4 and maximum 36, with median 20. State the range of the data.
- 15th July 2003A data set of ages is: 12, 13, 12, 14, 13, 99. Which value is most likely an outlier?
- 16th July 2003A city's population grows from 50,000 to 52,000 in one year. Find the percentage rate of change.
- 17th July 2003A company has 60 male and 90 female employees (150 total). A stratified sample of 30 employees is taken. How many males should be sampled?
- 18th July 2003Using the same table (0:4, 1:10, 2:4, 3:2), find the total number of students.
- 19th July 2003Two classes sit the same test. Class P: mean 70, range 10. Class Q: mean 55, range 30. Write a full comparison.
- 20th July 2003An item has an index number of 88 compared to its base year. State whether the value has increased or decreased, and by what percentage.
- 21st July 2003An event has a probability of 0.2 of happening. What is the probability that it does not happen?
- 22nd July 2003Using the relative frequency from the spinner above, estimate how many times it would land on blue in 300 spins.
- 23rd July 2003A spinner has P(win) = 0.3. It is spun twice, independently. Find the probability of winning both times.
- 24th July 2003On a population pyramid, which axis shows the age groups?
- 25th July 2003A box plot shows a long whisker on the left and a short whisker on the right, with the median close to the right of the box. What type of skew does this suggest?
- 26th July 2003A survey of 30 shoppers out of 900 in a store found the mean amount spent was 18.50 pounds. What is the best estimate of the mean amount spent by all 900 shoppers?
- 27th July 2003Find the median of 8, 3, 15, 3, 10.
- 28th July 2003A school of 600 students wants a sample of 30. A teacher decides to only survey students in her own class of 30. State one problem with this method.
- 29th July 2003A scientist tests a new plant food but only uses it on the healthiest-looking plants. Explain why this is a flawed design.
- 30th July 2003The frequencies for four class intervals are 6, 9, 11, 4. Find the total number of data values.
- 31st July 2003In a pie chart representing 120 people, 30 people chose 'Yes'. What angle represents 'Yes'?
