A researcher conducts an experiment on the secretion of a particular hormone in mice. Scientists inject mice with a substance that stimulates the production of the hormone. The scientists then test the levels of hormones produced by the mice. The tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. This tool makes______ measurements, but the measurements aren’t _____.

first blank options:
1.)qualitative
2.)Reliable
3.)Valid

second blank options

Answer: reliable; valid

...... This tool makes reliable measurements, but the measurements aren’t valid

Explanation:

For first blank:

In scientific research, once all necessary precautions have been taken, results obtained are usually represented as a range of possible values, and considered reliable

For instance

Let the level of the hormone analyzed to be X, then X±10 is said to be RELIABLE, because any of the values that falls higher or below X by 10points can be considered as the actual level.

For second blank:

The measurements are not valid because a gap or deviation of 10points from the actual value is too wide i.e giving room for errors.

And note that Valid measurements should be within a range of X±2

Answer: For the first blank Reliable. For the second blank Valid.

Explanation: I took the test and got it right:)
