Careful analysis of a random sample of n=25 Pages of a huge government document published by the office of printed statistical information revealed a mean of 5.2 spelling and/or Errors of grammar per page and the sample standard deviation of the number of errors per page is 3.8. Does this data provide significant evidence at the 5% level that the true mean numbers of errors per page is less than 7 and thus good enough for government work? State null and alternative hypothesis calculate the test statistic determine the P value state your conclusion
