Valentin [98]

Considering the situation described, the hypothesis tested are given as follows:

  • The null hypothesis is H_0: \sigma \geq 23
  • The alternative hypothesis is H_1: \sigma < 23

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if the standard deviation is not less than $23, that is:

H_0: \sigma \geq 23

At the alternative hypothesis, it is tested if there is significant evidence t conclude that the standard deviation is less than $23, that is:

H_1: \sigma < 23
