Generate THREE (3)EIGHT (8) > set_A <- runif(n=8, min=0, max=100) sets of data (Set A to C) from a random function using RStudio. Each set consists of data. All data should be between 0 to 100. The following R codes in RStudio show a sample of how to generate data randomly and display the data for Set A.
> format(round(set_A, 2)) # Apply 2 decimal format function
Screenshot the four sets of data and put it in.
The three sets of data generated represent aflatoxin content in 8 samples from 3 brands of peanut butter. Perform an analysis of variance to test at a 0.05 level of significance whether the three brands differ in aflatoxin content. Your answer must follow the structure below and in hand-written form.
a. State the hypotheses and identify the claim.
b. Find the critical value(s).
c. Compute the test value.
d. Make a decision.
e. Summarize and conclude the results.
Speed of light. In 1882 Michelson measured the speed of light (usually denoted c as in Einstein s famous equation E = mc2). His values are in km/sec.

If possible, determine a 95% confidence interval for average number of television sets in all 50,000 households. If this is not possible, describe why not.
You read a report that says, "On the basis of the simple random sample of 100 high school seniors that took the SATM test this year, a confidence interval for µ is found to be 512.00 ± 25.76." What was the confidence level used to calculate this..
Given a one-argument procedure p and an object a, p is said to ``halt'' on a if evaluating the expression (p a) returns a value (as opposed to terminating with an error message or running forever).
1. A particular event has a probability of occurrence of p=0.65. Given 12 independent trials, draw the probability distribution and calculate the expected value
the upper limit of the 95 confidence interval for the population proportion p given that n 300 and hat p 0.10 is
