just need part 3!

SAT scores: The College Board reports that in 2018 the mean score on the math SAT was 527 and the population standard devation was 0 = 114 , A random sample of 20 students who took the test in 2019 had a mean score of 549 . Fotioning is a dotplet of the 20 scores. (a) Are the assumptions for a hypothesis test satsied? No, the sample size is too smalt and the sample does not apoear to come from a (a) Are the assumptions for a hypothesis test satisfied? No, the sample size is too small and the sample does not appear to come from a population with an approximately normal distribution. Yes, the sample size is large enough to perform the test, whether or not the population is normally distributed. Yes, the sample size is small, but we can see that the sample seems to come from a population with an approximately normal distribution. (b) Perform a hypothesis test to determine whether you can conclude that the mean score in 2019 differs from the mean score in 2018 . Assume the population standard deviation is =114. Use the =0.10 level of significance and the P-value method with the - 84 . Plus caloulator. State the null and alternate hypotheses. H0:=527 (b) Perform a hypothesis test to determine whether you can conclude that the mean score in 2019 differs from the mean score in 2018 , Assume the population standard deviation is a 114 , Use the a =0.10 level of significance and the P-value method with the 7184 Pfus calculator? 5tate the null and alternate hypotheses. Compute the value of the test statistic. Round the answer to two decimal places. z= Pait: 3/6 Cornpute the P-value, Round the answer to ar least four decimal places
