Typo. Where the intro says

For a p-value of 0.05, if the null hypothesis is true, then the probability of obtaining a significant result is 1 – 0.05 = 0.95.

For a p-value of 0.05, if the null hypothesis is true, then the probability of obtaining a correct (insignificant) result is 1 – 0.05 = 0.95.
