Data on investments in the high-tech industry by venture capitalists are compiled by a corporation. A random sample of 18 venture-capital investments in a certain business sector yielded the accompanying data, in millions of dollars. Determine and interpret a 95% confidence interval for the mean amount, μ, of all venture-capital investments in this business sector. Assume that the population standard deviation is $1.85 million.
