O < > A myopenmath.com MyOpenMath b Answered: 40 married couples without children are... | bartleby The college of science at a particular university has 351 alum in a given year. Each of them are sent a survey after they graduate, and 27 of them are returned. The survey asks many things, chiefly among them how prepared they feel enterring the real world upon graduation. The results (on a scale of 1-10) show an average of 7.3 with a standard deviation of 2.7. Is there significant evidence to conclude that the scores of these recent graduates is different from 7 at the 0.01 significance level? Note that there's evidence that this distribution is symmetric. What are the hypotheses? Ο Η: μ < 7 vs Η: μ 7 Ο H0: μ 7 vs H1 : μ 7 O Ho: µ <7 vs H1:µ > 7 O Ho: µ = 7 vs H1 : µ + 7 What is probability statement for the p-value? O P(Z > test statistic) P(T > test statistic) O 2P(Z + test statistic) 2P(T + test statistic) None of the above If the p-value were to be 0.11, state and justify your decision. Reject Ho because the p-value > a. Fail to reject Ho because the p-value > a. O Accept Ho because the p-value > a. O Fail to reject Ho because the p-value < a. O Accept Ho because the p-value < a. O Reject Ho because the p-value < a.

What level of concern do you have for the validity of your results? Questionable there is likely to be some response bias and n < 30 Valid while the sample size is less than 30, the symmetry in the distribution means this isn't a concern Questionable there is likely to be some nonresponse bias and n < 30 Questionable there is likely to be some response bias Questionable there is likely to be some nonresponse bias Questionable the sample size is less than 30 Submit Question ° 88
