Exercise 6. Estimating the standard error

The theory we just learned tells us what this standard deviation is going to be because it is the standard error of \(\bar{X}\).

Estimate the standard error given an expected value of 0.45 and a sample size of 100.

Have a go at this exercise by completing this sample code.

# Define `p` as the expected value equal to 0.45
p <- 0.45

# Define `N` as the sample size
N <- 100

# Calculate the standard error
