The t-test serves as a measure of the agreement between two measurements of the same quantity. Assuming that the measured quantities follow a normal distribution, their difference (discrepancy) will follow the same distribution.

Indicate the expected occurrence for the following cases.

The t-test serves as a measure of the agreement between two measurements of the same quantity. Assuming that the measured qu
follow a normal distribution, their difference (discrepancy) will follow the same distribution.
Indicate the expected occurrence for the following cases.
A discrepancy of 30 is expected to occur
Choose.
A discrepancy of 20 is expected to occur
Choose.
32% of the time.
A discrepancy of one o is expected to occur
0.3% of the time.
5% of the time.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
