A random variable has a normal distribution with mean and known variance 57. Consider the hypothesis test Ho: 25 versus H₁: <25. The sample mean X is 20. Compute the value of the sample size n that would cause us to reject the null hypothesis in favour of the alternative hypothesis at the 5% significance level Give your answer to 3 decimal places.
