A confidence interval for the mean

```
meanConfInt(
vector = NULL,
mean = NULL,
sd = NULL,
n = NULL,
se = NULL,
conf.level = 0.95
)
# S3 method for meanConfInt
print(x, digits = 2, ...)
```

- vector
A vector with raw data points - either specify this or a mean and then either an sd and n or an se.

- mean
A mean.

- sd, n
A standard deviation and sample size; can be specified to compute the standard error.

- se
The standard error (cna be specified instead of

`sd`

and`n`

).- conf.level
The confidence level of the interval.

- x, digits, ...
Respectively the object to print, the number of digits to round to, and any additonal arguments to pass on to the

`print`

function.

And object with elements `input`

, `intermediate`

, and `output`

,
where `output`

holds the result in list `ci`

.

```
meanConfInt(mean=5, sd=2, n=20);
#> ci.lo ci.hi
#> (mean=5.00) 4.06 5.94
