A survey of 20 British companies found an average annual expenditure on research and development of £3.7m with a standard deviation of £0.6m. A survey of 15 similar German companies found an average expenditure on research and development of £4.2m with standard deviation £0.9m. Does this evidence lend support to the view often expressed that Britain does not invest enough in research and development? Test at a 5% significance level whether Britain spends less on research and development compared to Germany.
