Run the R command y <- rchisq(1000,2). Then use your exploratory tools to identify which, if any of the following are correct. THERE ARE more than one correct answer.

Group of answer choices:

The distribution is unimodal.

The mean would be an appropriate measure of location.

The median would be an appropriate measure of location

The distribution is skewed to the right

The standard deviation would be an appropriate measure of spread.

Solutions

Expert Solution

solution:

Sol:

y <- rchisq(1000,2)

hist(y)

mean(y)

median(y)

boxplot(y)

mean for data is 1.981126

median=1.380834

mean>median

skewed to right

From

boxplot we could see outliers

median would be appropriate measure of centre

Rscreensht

median would be an appropriate measure of location

The distribution is sewed to right

please give me thumb up

DISPLAYING AND DESCRIBING DISTRIBUTIONS In this lab assignment you will use exploratory tools in StatCrunch to study the wealth and life expectancy in 97 countries. In particular, you will learn how to display the related categorical and quantitative data with pie charts, histograms, and boxplots, and how to summarize the data by obtaining contingency table, mean, median, standard deviation, and quartiles. You will also explore the relationship between material wealth and life expectancy with a scatter-plot. Wealth and Life Expectancy...

Consider our medium-run model of the economy: Y =C(Y −T)+I(Y,r+x)+G (IS) r=r(bar) (LM) πt − πt − 1 = −α(ut − un) (PC) Suppose the economy starts at a point such that ut = un and r=rn Graph the effects of a financial shock that increases the risk premium, x. What happens to output, the interest rate, and inflation in the short-run? What happens in the medium-run? What mechanism causes the transition from the short-run equilibrium to the medium-run equilibrium?
