f.Which measure of center (mean or median) is more appropriate for these data?Why? Consider the shape of the distribution discussed in part c.8h.Calculate the standard deviation of the annual income data.Calculate the interquartile range of the annual income data.Visualizing Two VariablesLet's continue to explore the annual income data, but now consider how annual income datamay vary between loan status (current or fully paid).Construct a side-by-side boxplot for annual income broken up by loan status. Includeinformative labels and a title.J.How do the distributions of annual income compare for loan status? Comment onthe shape, center, spread, and presence of outliers for the two groups.k.Exploring a Single Categorical VariableFinally, we'll focus our attention only on the loan status variable.Construct a table of counts for the loan status variable. Report the number ofobservations in each category below.I.Construct a table of proportions for the loan status variable. Report the proportionsfor each category below.Construct a barplot that displays the distribution of loan status types. Includeinformative labels and a title. Include your barplot below. Part 2 of the Introduction to RStudio & Tutorial uses two variables from the Lending Club data:loan amount and homeownership. For the assignment you'll submit, you will practice usingtwo different variables. Please make sure the assignment you submit uses the correct variables(specified in the questions below).Exploring a Single Quantitative VariableFor this portion of the assignment, you'll practice using R to explore the annual_incomevariable in the loan50.csv data set.a.Construct a histogram of the annual income data. Include informative labels and atitle. Include your histogram below.b.Construct a boxplot of the annual income data. Include informative labels and atitle. Include your boxplot below.C.Using the histogram you constructed in part a and the boxplot from part b, describethe shape of the distribution of the annual income variable and comment on the presence ofany outliers.d.e.Calculate the mean of the annual income data.Calculate the median of the annual income data.

Major Vegetables and Root Crops Quarterly Bulletin, April-June 2023 September 2023 Production of cabbage during the second quarter of 2023 was registered at 23.33 thousand metric tons. This represents a decrease of -4.5 percent from the 24.44 thousand metric tons recorded output in the same quarter of 2022. CAR was the leading producer of cabbage with 18.50 thousand metric tons or 79.3 percent share to the total production during the quarter. This was followed by Central Visayas with 1.38 thousand metric tons or 5.9 percent share. The January to June 2023 area harvested for cabbage was estimated at 2.94 thousand hectares. This was 0.6 percent higher than the same period of previous year’s level of 2.92 thousand hectares. what is the cause of the decrease in production? what is the critical baguio vegetable production has decreased these past few years?

For this question, create a new column in the dataset where total rainfall is just the sum of our three separate rainfall variables. (a) plot crop yield vs. time. Does yield appear to be stationary? Why or why not? (b) plot total rainfall vs. time. Does total rainfall appear to be stationary? Why or why not? (c) plot the first-difference of crop yield vs. time. Does this series appear to be stationary? Why or why not? (d) formally test whether crop yield, rainfall and the first-difference of crop yield are stationary using the appropriate test. Be sure to do all parts of the hypothesis tests. After these tests, what can you say the order of integration is for each of the variables?(e) estimate a model where yield is a function of rainfall and time. You do not have to worry about the time variable being stationary or not, but the other two must be stationary (you might need to difference one or both of them to make it stationary). Fully report your results.(f) test your model for…
