- From your readings in the chapter or other online research, comment on the concept of the standard normal distribution. Address one of these issues: standard-ness; normality; uniformity; parameters; the mean; the relationship to the variance; the importance of the standard normal distribution; what the standard normal distribution is; skewness; or consistency. Title your post with the issue that you are going to address. Cite any sources utilized for your response.What are some examples of measures that you think may be normally distributed?

- list five different things that are normally distributed. Examples that you can't use since I came up with them: Shoe size, middle finger length, oxygen level, electricity bill, wait times on line to pay at target. You must give the website where you found that they are normal for each one of them. 2) measure yourself and use the normal distribution to find out what percent of the population is less than use. What this means is that for one of the five things in 1) you need to make sure that you can find the mean and standard deviation. So an example would be: I found the oxygen level mean and standard deviation to be 98.3 and 1.1. My oxygen level is 98.9. Using the normal distribution calculator I found that 69.3% of the population has a lower measure of that. Help …. I don’t understandAn immunologist wants to compare two rabies vaccines. People who had previously received the vaccine were divided into two groups. The first group received a booster dose of type I vaccine and the second group received a booster dose of type II vaccine. Two weeks later the antibody level was measured. The average number of antibodies in each group appears in the following table Do these data indicate that there is a difference in the effectiveness of the two vaccines used for booster doses? Assume a normal distribution and equal population variances. The test statistic that will determine if there is a difference in the effectiveness of the two vaccines..... A. 2,579 B. 2.76 C. 0.58 D. 0.787If a set of observations is normally distributed, what percent of these differ from the mean by (a) more than 2.20? (b) less than 0.32g?
