### Problem 3 HW3 RStudio b) c) d) The pH of a liquid is a measure of its acidity or alkalinity. Pure water has a pH of 7, which is neutral. Solutions with a pH less than 7 are acidic while solutions with a pH greater than 7 are basic or alkaline. The dataset FloridaLakes gives information, including pH values, for a sample of lakes of Florida. The dataset may be downloaded from the following address (http://www.lock5stat.com/datasets/FloridaLakes.csv).

a) Download the dataset and read it. Use the variable datalakes to represent the data. How many different fields the dataset contains?

```{r} datalakes=read.csv("http://www.lock5stat.com/datasets1e/FloridaLakes.csv") datalakes ```

b) Obtain the summary of the dataset in regards to the values of pH (mean value, standard deviation, sample size, minimum, maximum, median, first quartile, third quartile)

```{r} # Insert R code here

```

c) How many lakes are included in the dataset? What is the mean pH value? What is the standard deviation?
