using rstudio Mutate Q10. Which command calculates the body mass index (BMI) of characters in the starwars data.frame and stores the results in a new variable called BMI? (Hint: BMI = mass/height^2 where mass is in kg and height is in m) A. starwars %>% mutate(mass*height^2) B. BMI % mutate(mass/(height/100)^2) C. starwars %>% mutate(BMI = mass/height^2) D. starwars %>% mutate(BMI mass/(height/100)) E. starwars %>% mutate(BMI = mass/(height/100)^2) %3!

Event Listeners Go to the co_credit.js file in your editor. Create an event listener for the window load event that retrieves the field values attached to the query string of the page’s URL. Add the following to the event listener’s anonymous function: Create the orderData variable that stores the query string text from the URL. Slice the orderData text string to remove the first ? character, replace every occurrence of the + character with a blank space, and decode the URI-encoded characters. Split the orderData variable at every occurrence of a & or = character and store the substrings in the orderFields array variable. Write the following values from the orderFields array into the indicated fields of the order form: orderFields[3] into the modelName field orderFields[5] into the modelQty field orderFields[7] into the orderCost field orderFields[9] into the shippingType field orderFields[13] into the shippingCost field orderFields[15] into the subTotal field orderFields[17]…
Write a function named copyInput that that doesn't take any parameters and doesn't return a value. This function should find an HTML element with an id of "user_input".

In R, please provide the code for the following: Install the ggpubr package. Load the islands data set; note that the units are in 10,000s of square miles (so a value of 14 indicates 14,000 square miles) Generate a qq plot, with a reference line, of the landmass in square miles of the islands (landmasses) in the data set. What can you conclude about the distribution of the sizes and which tests will and will not be appropriate for this data set? Use the sample function to create 5 different samples of size 15 from the islands data set. You will use these samples for the remainder of the lab. Plot boxplots of all 5 data sets on the same graph, with each boxplot being a different color. Clearly label your sets 1-5, and use this same ordering to present your results in the rest of this problem. Make a dataframe with one column that has the sample number (1-5) and another column with the data. Make sure you have named your columns. An example where sample1 is the first sample of 15 points…
