Question 10 View Policies Current Attempt in Progress A random sample of 17 observations taken from a population that is normally distributed produced a sample mean of 58.5 and a standard deviation of 7.5. Find the range for the p-value and the critical and observed values of for the following test of hypothesis, using a = 0.01. Ho: = 55 versus H: 55. Round your answers for the values of t to three decimal places. critical left critical right i observed i
EXPERT ANSWER Answer) Given test is two tailed N = 17 Degrees of freedom is = n-1 = 16 For 16 dof and 0.01 alpha (two tailed) Critical values t from t table are -2.921 and 2.921 tcritical left = -2.921 tcritical right = 2.921 t observed = (sample mean – claimed mean)/(s.d/√n) t = …
