(Using R Scholar) For each of the distributions, begin by creating 1000 random samples, each of size ?. Then, for each of the 1000 samples, you will calculate the sample average, ?̅. After calculating 1000 different ?̅’s, you will be able to make a histogram and normal probability plot of the ?̅ values and thus visualize the distribution of ?̅. The goal is to see what value of ? is large enough for the distribution of ?̅ to become approximately...

For expert using R I try to solve this question((USING DATA FAITHFUL)) but each time I solve it, I have error , I try it many times. So,everything you write will be helpful.. Modify the EM-algorithm functions to work for a general K component Gaussian mixtures. Please use this function to fit a K= 1;2;3;4 modelto the old faithful data available in R (You need to initialize the EM-algorithm First ).    Which modelseems to t the data better? (Hint:...

Eight chemical elements do not have isotopes. A random sample of 30 of the elements that do not have isotopes showed a mean number of 19.63 isotopes per element and the population has a standard deviation of 18.73. Estimate the true mean number of isotopes for all elements with isotopes with 90% confidence. (5 pts) How would I solve this? What formula would I use?

Using R Studio/R programming... Usually, we will use a random sample to estimate the statistics of the underlying population. If we assume a given population is a standard normal distribution and we want to estimate its mean, which is the better technique to estimate that mean from a sample: Use the mean of one random sample of size 500 Use the mean of 300 random samples of size 10 Run your own experiment and use your results as a supporting...

How do you solve this using R? The file "flow-occ.csv" contains data collected by loop detectors at a particular location of eastbound Interstate 80 in Sacramento, California, from March 14-20, 2003. For each of three lanes, the flow (the number of cars) and the occupancy (the percentage of time a car was over the loop) were recorded in successive five-minute intervals. There were 1740 such five-minute intervals. Lane 1 is the farthest left lane, lane 2 is in the center,...
