Printing for a group?
The batch download puts all 2 tiers' September 2000 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in September 2000
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st September 2000A pictogram key shows 1 symbol = 4 books. A row has 2 and a half symbols. How many books does the row represent?
- 2nd September 2000Two fair coins are flipped. How many equally likely outcomes are in the sample space?
- 3rd September 2000A frequency table has classes 0-10, 10-20, 20-30 with frequencies 3, 9, 6. State all three coordinates for the frequency polygon.
- 4th September 2000On a time series graph, what is always plotted on the horizontal axis?
- 5th September 2000Group A has a risk of 0.08 of an event happening; Group B has a risk of 0.02. Find the relative risk of Group A compared with Group B.
- 6th September 2000A bag has 3 red, 4 green and 5 blue balls (12 total). One ball is removed at random and is blue. A second ball is then removed. Find P(second ball is red given the first ball was blue).
- 7th September 2000A 3D pie chart is used to show market share. Explain why 3D charts can be misleading.
- 8th September 2000A table has class intervals with frequency x midpoint totals of 45, 120, 90 and frequencies 5, 8, 6. Find the estimated mean.
- 9th September 2000Explain why a pilot survey should be carried out before the full survey is sent out.
- 10th September 2000Find the 4-point moving average of 12, 16, 20, 10.
- 11th September 2000P(rain) = 0.3 and P(snow) = 0.05 on a given day, and rain and snow are mutually exclusive that day. Find P(rain or snow).
- 12th September 2000Using the same histogram, how many students scored between 10 and 30 marks?
- 13th September 2000A box plot has lower quartile 10 and upper quartile 22. Find the interquartile range.
- 14th September 2000The heights (cm) of 6 plants are: 15, 18, 16, 14, 17, 150. Find the mean of the remaining values after removing the outlier.
- 15th September 2000Explain why a crude rate is more useful than a raw total, such as the total number of deaths, when comparing two towns of different sizes.
- 16th September 2000A factory has 400 workers: 160 in production, 120 in packing and 120 in admin. A stratified sample of 50 workers is needed. Find how many should be sampled from packing.
- 17th September 2000Using the same table (0:4, 1:10, 2:4, 3:2), find the mean number of siblings.
- 18th September 2000The mean rainfall in April was 45 mm with a range of 20 mm; in May it was 45 mm with a range of 8 mm. Compare April and May.
- 19th September 2000A cost index for electricity, relative to the same base year, was 120 in 2021 and 150 in 2023. Find the percentage increase in the cost of electricity from 2021 to 2023 (not from the base year).
- 20th September 2000The probability that a train is late is 0.15. Out of 200 trains, how many would you expect to be late?
- 21st September 2000The probability that a machine produces a faulty item is 0.04. Out of 300 items, how many would you expect to be faulty?
- 22nd September 2000A box has 3 faulty bulbs out of 10. Two bulbs are chosen without replacement. Find the probability at least one is faulty.
- 23rd September 2000In a pyramid, the bars for ages 65+ are unusually long compared with younger age bands. Give one possible reason.
- 24th September 2000A data set has mean 12, median 12, mode 12. Describe its skew.
- 25th September 2000A sample of 80 light bulbs from a batch of 2000 found 4 were faulty. Estimate the number of faulty bulbs in the whole batch.
- 26th September 2000The mean of 6 numbers is 15. Five of the numbers are 10, 12, 14, 18, 20. Find the sixth number.
- 27th September 2000State one advantage of random sampling.
- 28th September 2000What is meant by a control variable?
- 29th September 2000Values of 12, 18, 25, 31, 9, 22, 15 are grouped using intervals 0 <= x < 10, 10 <= x < 20, 20 <= x < 30, 30 <= x < 40. State the frequency of the interval 10 <= x < 20.
- 30th September 2000A pie chart shows four categories with angles 90, 120, 60 and x degrees. Find x.
