Select all the following which are true. Marking: canvas marks as follows: If there are k correct answers, and you select answers of which X₁ are correct, and X₂ are incorrect, then Your mark is X₁ X2 k k The x²-distribution is the sum of squared standard normal distributions. The X²-distribution is the sum of independent standard normal distributions. The F-distribution is the ratio of two x²-distributions. The t-distribution is the ratio of a standard normal and a x²-distribution. The t-distribution is the ratio of a standard normal and a x²-distribution, divided by its degrees of freedom. The x²-distribution is the sum of independent, squared standard normal distributions. The F-distribution is the ratio of two x²-distributions, each divided by its degrees of freedom. The t-distribution is the ratio of a standard normal and the square root of a x²-distribution divided by its degrees of freedom. The F-distribution is the square root of the ratio of two x²-distributions, each divided by its degrees of freedom. Select all the following which are true.
