Question

Questions 16-17. Consider a random sample ( X_{1}, X_{2}, ldots, X_{9} ) selected from a normal population with mean ( mu ) and variance ( sigma^{2} ). Let ( ar{X} ) be the sample mean and ( s^{2} ) be the sample variance. 17. Which range of values includes ( P(ar{X}>mu+s) ) ? (a) 0 and 0.005 ( sqrt{ } ) (b) 0.005 and 0.01 (c) 0.01 and 0.02 (d) 0.02 and 0.025 (e) 0.025 and 1

Step 1

In this case, \( n = 9 \). Second, we are interested in the probability that \( \bar{X} \) is greater than \( \mu + s \). This is equivalent to the probability that \( \bar{X} - \mu \) is greater than \( s \). Third, we know that \( \bar{X} - \mu \) follows a Show more…
