Question 36
ESMCQ2 marksNeeds review
W₁, W₂, W₃...W₉ represent the holding times of 9 water samples, which follow a normal distribution with mean = 8.33 and standard deviation = 4.472. M represents the sample mean value of holding times, which also has a normal distribution. Assuming Z has a standard normal distribution (mean = 0 and standard deviation = 1), select the correct statement which describes the expression for calculating the value of type 1 error where
null hypothesis (H₀): M > 6
alternate hypothesis (Hₐ): M ≤ 6
