# Question: A random sample of size n 25 from a

A random sample of size n = 25 from a normal population has the mean x = 47 and the standard deviation σ = 7. If we base our decision on the statistic of Theorem 8.13, can we say that the given information sup–ports the conjecture that the mean of the population is µ = 42?
