Lab 4 - The Normal Distribution Solution
```{r setup, include=FALSE} knitr::opts_chunk$set(echo = TRUE) library(tidyverse) library(openintro) ``` For exercise 1 & 2, don't remove points for not including `mean = 0` and `sd = 1` as it is just the standard normal. For exercise 3, 4 & 5, remove a point each if they don't have the right numbers such as the cut off point, mean and sd. Same with the function as well. ## Exercise 1 (4 Points) ```{r, warning=F, message=F} pnorm(-0.33, mean = 0, sd = 1) ``` ## Exercise 2 (4 Points) ```{r, warning=F, message=F} pnorm(1.89, mean = 0, sd = 1) - pnorm(-1.89, mean = 0, sd = 1) ``` ## Exercise 3 (4 Points) ```{r, warning=F, message=F} 1 - pnorm(83, mean = 77, sd = 5) ``` ## Exercise 4 (4 Points) ```{r, warning=F, message=F} qnorm(0.10, mean = 77, sd = 5) ``` ## Exercise 5 (4 Points) ```{r, warning=F, message=F} qnorm(0.95, mean = 77, sd = 5) ```
