Animals of a given weight are operated on in a veterinary hospital. The dose of anesthetic A (in mg) required to render animals suitably unconscious for the operation is normally distributed with mean 120 and standard deviation 20. The lethal dose L (in mg) of the same anesthetic for these animals is also normally distributed, with mean 350 and standard deviation 50. (Help on part a and b) a. Find a dose "D" that the vet should administer, in order that 99.9% of animals will be suitably unconscious for the operation. b. If the dose "D" that you found in part a is administered, what percentage of animals die?

You will be comparing two sets of data for this assignment. 1. Determine the average number of toilet paper rolls* for Fall 2022 biochemistry and genetics students (individually) and calculate the standard deviation of each using the equation. Please be sure to show your work. I know that you can easily use tools like Microsoft Excel to calculate standard deviation, but I would like to see you complete the work by hand so that you get a sense of the role of each component of the equation. Ignore students that did not provide answers (don't use those students in the mean or N value calculations). 2. Please answer the following questions when you submit your data. Which group had a higher mean number of rolls of toilet paper? Which value had the most variability? Referring to the equation, how could you decrease the amount of variability in the mean? Did you find the variation surprising or unexpected? The two sets of data and the standard deviation formula pictures are attached…

SOLVE STEP BY STEP IN DIGITAL FORMAT, DON'T USE CHATGPT A researcher in criminology is interested in determining whether the average age of offenders in a particular population has changed in recent years. The researcher collects a sample of 100 offenders and calculates that the average age of the sample is 30 years. The standard deviation of the population is known to be 5 years. The researcher wants to test whether there is evidence of a significant change in the average age of offenders, using a significance level of 0.05. Ask: What is the null hypothesis (H0) and alternative hypothesis (H1) in this study? Also, what type of statistical test would be used and what is the process for performing the test with a Z statistic? Perform the necessary calculations and put your conclusions.
