I'm not sure if Q4 is correct also having trouble with starting Q5 I'm new to data science

## Q4: Create a copy of my_fam_heights, called `new_fam_heights`. Change the 3rd value to 2.2 and store new_fam_heights as Q4.

```{r} ### Do not change and do not delete the comment below. It is required for Code Grade to run properly. # CG Q4 #

### TYPE YOUR CODE BELOW ###

my_fam_heights <- c(1.5, 1.7, 1.8, 1.9)

new_fam-heights <- my_fam_heights

new_fam_heights[3] <- 2.2

### VIEW OUTPUT ### Q4

```

## Q5: Create Q5 with the mean (i.e. average) of Q4.

```{r} ### Do not change and do not delete the comment below. It is required for Code Grade to run properly. # CG Q5 #

### TYPE YOUR CODE BELOW ###

### VIEW OUTPUT ### Q5

## Q6: Round Q5 to one decimal place and assign the result to Q6.

```{r} ### Do not change and do not delete the comment below. It is required for Code Grade to run properly. # CG Q6 #
