In a farming community, 30% of the farmers grow oranges only, 10% grow lemons only and 4% grow both oranges and lemons.
1.1) What proportion of farmers in the community grow either oranges or lemons? [3 marks]
1.2) If a farmer is chosen randomly from these in the community, what is the probability that he grows neither oranges nor lemons? [2 marks]
1.3) Of all the farmers who grow oranges, what proportion grow lemons also? [2 marks]
Diameters of bolts produced by a particular machine are normally distributed
with mean 0.760 cm and standard deviation 0.012 cm. Specifications call for
diameters from 0.720 cm to 0.780 cm.
A government agency was charged by the legislature with estimating the length of time it takes citizens to fill out various forms. Two hundred randomly selected adults were timed as they filled out a particular form. The times required had mean 12.8
minutes with standard deviation1.7 minutes. Construct a 90%
confidence interval for the mean time taken for all adults to fill out this form.
A magazine reported that 3% of Turkish drivers smoke while driving. If 300 drivers are selected at random,
find the probability that 4 or 5 drivers accept that they smoke while driving. Use all possible calculation methods
and justify them with sufficient explanation.
The reaction time of a driver to visual stimulus is normally distributed with a mean of 0.4
seconds and a standard deviation of 0.05 seconds. Use R to find the
(a) probability that a reaction requires more than 0.5 seconds.
(b) probability that a reaction requires between 0.4 and 0.5 seconds.
