Which of the following regarding the assumption of sphericity is false? (Hint: Even very small departures from sphericity produce large biases in the F-test.)
Sphericity does not affect post hoc tests.
The effect of violating sphericity is a loss of power (i.e., an increased probability of a Type II error).
When sphericity is violated, we need to adjust the degrees of freedom for any F-ratios affected by the violation.
When sphericity is violated, the Bonferroni post hoc test can be used.

As an x-ray tube ages, the inside can become coated with tungsten, which can cause arcing in the tube.
When there is a short circuit inside the tube, usually from the cathode to the tube envelope, tube arcing happens. A brief loss of x-ray output and a localised artefact are the consequences. On transaxial computed tomography (CT) scans, it appears as a near-parallel, equidistant streak pattern, and on coronal and sagittal CT images, as a "horizontal" hypodense band.
The most frequent cause of x-ray tube failure is an inability to effectively disperse the heat produced during routine operation. It is common knowledge that at the anode target, heat accounts for 99% or more of the kinetic energy given to the electron beam.
Therefore, an x-ray tube ages, the inside can become coated with tungsten, which can cause arcing in the tube.

Answer: Prevalence measures
Explanation:
The primary method that is used to measure the existence of states of a particular health or illness with regards to a population at a given time period is referred to as prevalence measure.
The prevalence measures simply refers to the proportion of individuals that have a particular disease at a particular period of time in a population.
