In the Research paper, "Immunogenicity and safety of a recombinant adenovirus type-5-vectored COVID-19 vaccine in healthy adults aged 18 years or older; a randomized, double-blind, placebo-controlled, phase 2 trial" published by The Lancet, August 15, 2020. One of the outcomes evaluated for immunogenicity (the ability to produce an immune response) of the vaccine was to measure the mean RBD-specific ELISA antibody responses of the trial participants 28 days post vaccination. The trial randomly placed participants into 1 of 3 vaccine groups (vaccine 1, vaccine 2, and placebo group). The paper reports, with 95% confidence, at day 28 post vaccination, the mean RBD-specific ELISA antibody response detected in all participants receiving vaccine 1 is between 575.2 and 749.2 GMT. Answer the following questions regarding this trial result:

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
