## 1. What is the average gestation period for all mammals?

```{r}
# mean()

```

**Your interpretation:**

## 2. What is the median gestation period for all mammals?

```{r}
# median()

```

**Your interpretation:**

## 3. Construct a histogram and describe the shape of the gestation period for all mammals. Use a horizontal boxplot to identify whether there are any outliers present.

```{r}
# Histogram

# Horizontal boxplot

```

**Your interpretation: Describe the shape and whether outliers are present.**

## 4. Which is more spread out, body weight or brain weight?

```{r}
# Compare standard deviations using sd()

```

**Your interpretation:**

## 5. Construct horizontal boxplots for total sleep, lifespan, and gestation. Which of these variables are the most symmetric?

```{r}

```

**Your interpretation:**

## 6. Create a new data set of small mammals named 'smam' consisting only of mammals whose body weight is less than 100.

```{r}
# filter()

```

## 7. Create a new data set of large mammals named 'lmam' consisting only of mammals whose body weight is at least 100.

```{r}

```

## 8. Create a scatterplot of the gestation vs. total sleep for large mammals. Comment on the type of association. Find the correlation coefficient.

```{r}
# Scatterplot using plot()

```

**Your interpretation:**

```{r}
# Correlation using cor()

```

**Your interpretation:**

## 9. Which sleeps more, small mammals or large mammals?

```{r}
# Compare means

```

**Your interpretation:**

## 10. Create a scatterplot of the body weight vs. brain weight for small mammals. Which mammal is the influential point?

```{r}

```

**Your interpretation:**
