Suppose you had a dataset (assigned to data frame object called df). df has 100 observations with a single numerical column called col1. col1 value of each observation is equal to 10. You then run the following code: df$col2 <- df$col1 df$col1 <- 0 mean(df$col2) What did R output when the entire code was executed successfully? [Fill in the blank]

Suppose you have given a subset of our North American Stock Market dataset in a data frame called compdf. There are all the 50 columns. Similar to our North American Stock Market dataset, gvkey and fyear combination uniquely identifies each observation in compdf. If you execute length(unique(compdf$loc)), you are returned 7. If you execute compdf %>% group_by(gvkey) %>% summarise(count = n()) , all the values under count column are 20. Suppose you executed the following code successfully. df1 <- compdf %>% group_by(loc, fyear) %>% summarise(stat1 = mean(at, na.rm = TRUE), stat2 = max(stat1)) df1 should have [Fill in the blank] rows and 4 columns.

Suppose you had a dataset (assigned to data frame object called df). You know that it has 100 observations with a single numerical column called a. All observations for a are equal to 100. You then run the following code: df$b <- df$a df$a <- 0 mean(df$a != df$b) What did R output when the entire code was executed successfully? [Fill in the blank]
Suppose df has 30 rows with 3 numeric columns named d, e, and f. When you executed length(which(df$d >= 5)) the output returned is 20. Then, you executed df <- df %>% mutate(d = if_else(d >= 5, 5, 0)) TRUE/FALSE: When you execute the following line of code, the result returned can be less than 10. length(which(df$d == 0))
Assume that you run the following code. just_above_ave = min(student$grade[which(student$grade >= mean(student$grade))]) Then, you decided to get the same result in an alternative way. df5 <- student %>% filter(grade >= mean(grade)) %>% summarise(min(grade)) the value in df5[1,1] is equal to just_above_ave.
