Criminal investigators use biometric matching for fingerprint recognition, facial recognition, and iris recognition. when matching fingerprints, each subject is given a mean match score for how well their fingerprint matches the given fingerprint, based on different criteria. there are six criteria used to calculate the match score. the mean match score used by a particular police department is 80. if the police department finds a higher match score than this number, they consider the person a fingerprint match and a suspect in the crime. the null hypothesis is that the mean match score is 80. the alternative hypothesis is that the mean match score is greater than 80. is the following a type i error or a type ii error or neither? the test shows that the mean match score is more than 80 when the person does not actually have a fingerprint match.

Submarines control how much they float or sink in the ocean by changing the volume of air and water contained in large ballast tanks. when the tanks are completely full of water, the submarine increases its overall mass and sinks down to the bottom. when the tanks are completely full of air, the submarine reduces its overall mass and floats to the surface. depending on the density of the seawater surrounding the submarine, it will pump seawater in or out of the tanks in order to achieve the same overall density as the sea water and float neutrally in the water. the volume of the submarine never changes. when the tanks are completely full of water, a submarine with a volume of 7.8\times10^3\text{ m}^37.8×10 3 m 3 7, point, 8, times, 10, start superscript, 3, end superscript, space, m, start superscript, 3, end superscript has a total mass of 8\times10^6\text{ kg}8×10 6 kg8, times, 10, start superscript, 6, end superscript, space, k, g. the density of the seawater is 10^3\text{ kg/m}^310 3 kg/m 3 10, start superscript, 3, end superscript, space, k, g, slash, m, start superscript, 3, end superscript. to make that submarine float neutrally, and neither float nor sink in the ocean, what volume of water does that submarine need to subtract from its tanks?
