A random sample of 88 eighth grade students' scores on a national mathematics assessment test has a mean score of 281. This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 275. Assume that the population standard deviation is 32. At a= 0.09, is there enough evidence to support the administrator's claim? Complete parts (a) through (e). (a) Write the claim mathematically and identify Ho and Ha. Choose the correct answer below.

A nationwide test taken by high school sophomores and juniors has 3 sections, each scored on a scale of 20 to 80. In a recent year, the national mean score for the writing section was 48.7, with a standard deviation of 10.6. Based on the information, complete the following statements about the distribution of the scores on the writing section for the recent year.
Assume that the SAT test scores are normally distributed with a mean score of 1200 and a standard deviation of 150. ACT test scores are normally distributed with a mean score of 22 and a standard deviation of 3 Mike scored 1250 on the SAT. What proportion of all test takers did Mike score higher than? If Mike scored a 1250 on the SAT and Jes scored a 26 on the ACT, then who's score is relatively better?
Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 78.6Mbps. The complete list of 50 data speeds has a mean of x=15.15 Mbps and a standard deviation of s=21.46Mbps. a. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the carrier's highest data speed to a z score. d. If we consider data speeds that convert to z scores between−2and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant?
