Test the hypotheses H:u<229 vs. H: > 220 with a significance level of 0.05, given that s = 15.5and that a sample of size 17 produced a sample mean of 231.175. Which of the following is the correct p-value and conclusion? O A. p = 0.004, reject Hol O B. Cannot determine normality; do not test O c.p=0.001 do not reject H ODP 0.004 do not reject Ho| The scores on a certain test can be modeled by a normal random variable with mean ji = 71 and standard deviation o = 121 What is the lowest score that a test-taker can achieve and still be in the top 10%? (Round your answer to three decimal places.) Lowest score =
