rnorm, dnorm, and the weight of newborns

Here is a small data set with the birth weights of six newborn babies in grams.

c(3164, 3362, 4435, 3542, 3578, 4529)

Let's assume that the Normal distribution is a decent model of birth weight data.

Given the birth weight data, what would be reasonable values of the mean (mu) and standard deviation (sigma) that generated this data?
Assign these value to mu and sigma.

No need to do anything fancy here, just eyeball the data and try to come up with something reasonable.

Remember: The standard deviation sigma describes the spread of the distribution, where around 70% of the drawn values will be within one standard deviation from the mean.
