A random sample of 18 venture-capital investments in a certain business sector yielded the accompanying data, in millions of dollars. Assuming that the population standard deviation is $1.79 million, a 95% condence interval for the mean amount, [1, of all venture-capital investments in this business sector is from $5.33 million to $6.98 million. Conditions for computing the condence interval are satised. Complete parts (a) through (d) below. (Note: The sum of the data is $110.76 million and the mean is $6.15 million.)

Find a 90% condence interval for p. The 90% condence interval is from $ million to $ million. (Round to two decimal places as needed.) b. Why is the condence interval you found in part (a) shorter than the 95% condence interval? The V used in computing the condence interval found in part (a) is V the corresponding value for the 95% condence interval.
