Practice Questions
Answer all questions. Show your working in the grid spaces provided.
1.
A scientist predicts that out of 200 plant seedlings, 60 will sprout within a week. How many seedlings do you expect will sprout? Show your calculation.
[2 marks]2.
A science experiment involves testing 150 drops of a new solution. The expected frequency of a certain reaction is 30%. How many drops are expected to show the reaction?
[2 marks]3.
If a sample of 250 insects is tested and 20% are predicted to carry a disease, how many insects are expected to be diseased?
[2 marks]4.
In a laboratory, 120 trials are conducted with an expected success rate of 75%. How many successes are predicted?
[2 marks]5.
A researcher expects 40% of 300 tested samples to show a positive result. Calculate the expected number of positive results.
[2 marks]6.
During an experiment with 500 trials, a scientist predicts 15% will fail. How many failures are expected?
[2 marks]7.
A scientist observes that in 180 trials, 36 are expected to show a specific reaction. What is the predicted proportion of reactions?
[2 marks]8.
You conduct 250 experiments and expect 80% success. How many experiments do you predict will succeed? Show your working.
