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 $1.80 million.

Click here to view page 2 of the table of areas under the standard normal curve. The 95% confidence interval is from $O million to $ million. (Round to two decimal places as needed.) Interpret the 95% confidence interval. Select all that apply. O A. 95% of all amounts of venture-capital investements in this business sector are between the interval's bounds. B. With 95% confidence, the mean amount of all venture-capital investments in this business sector is between the interval's bounds. O c. 95% of all possible random samples of 18 venture-capital investments in this business sector have mean amounts that are between the interval's bounds. D. There is a 95% chance that the mean amount of all venture-capital investments in this business sector is between the interval's bounds.
