I need help using r studio

## Question 1 Imagine that you are investigating the monitor lizards that inhabit Kangaroo island off the coast of Australia. You want to describe the probability distribution of the lengths of the island lizards. The file entitled "lizard.csv" contains data on body length (in cm) from a random sample of Kangaroo Island monitor lizards. make a script that does the following:

```{r} # Import the data.

# Estimate the mean of length by direct calculation.

# Estimate the mean with R's built-in function.

# Estimate the variance of length by direct calculation.

# Estimate the variance with R's built-in function.

# Estimate the standard deviation of length by direct calculation.

# Estimate the standard deviation with R's built-in function.

# Estimate the standard error of the mean length.
