Stat 200 Lab 15Go to the course web site www.stat.psu.edu/~rho/stat200/ , then use the link for the classdata set collected in the first survey (in January). The link takes you to a copy of thesurvey form that also has a link to the data. Link to the data. Copy and paste the data to aMinitab worksheet. Note that variable names are not present so paste to the first datacell. In order, the variables are :C1 SexC2 Ear Pierces (total number)C3 Tattoo?C4 CDs ( about how many owned)C5 HeightC6 Choice of HeightC7 Importance of Personality versus Looks (0 to 9 scale,0=personality very imp. 9=looks very important)C8 Section (1 to 4)C9 Easiest to Make Friends With ___ (Opposite Sex, Same Sex, No Diff.)Activity 1What is the proportion with a tattoo in each section? (Use Stat>Tables>CrossTabulation). (get four different proportions)Is there a statistically significant difference among the sections with regard to theproportion with a tattoo? (Go back to the Cross Tabulation dialog, click on Chi-Squaretest, also get expected counts)What is our null hypothesis?What is the p-value of the test? What is the conclusion?What do the "expected counts" measure?Page 2Activity 2Is there a statistically significant difference between males and females with regard to the"Easiest to Make Friends With" question in C9? Do a Chi-Square test. What is the p-value for the test? State a conclusionActivity 3Is there a statistically significant difference between the number of CDs owned by meanand women? Start by doing a 2-sample t to compare means (the samples are in onecolumn). State null and alternative hypothesis. State a conclusion about these hypotheses.What is the estimated difference between the means?Do a histogram of the CDs variable. Are the data skewed or symmetric? Should we beanalyzing means or
