The mean sat score in mathematics, m, is 600. the standard deviation of these scores is 48. a special preparation course claims that its graduates will score higher, on average, than the mean score 600. a random sample of 70 students completed the course, and their mean sat score in mathematics was 613. at the 0.05 level of significance, can we conclude that the preparation course does what it claims? assume that the standard deviation of the scores of course graduates is also 48.perform a one-tailed test. then fill in the table below. carry your intermediate computations to at least three decimal places, and round your responses as specified in the table. null hypothesisalternative hypothesistype of test statistic (if t, list the degrees of freedom)value of test statisticcritical value at the 0.05 level significance (round to at least three decimal places)can we support the preparation course's claim that its graduate score higher in sat? yes or noi understand that this may seem like multiple questions, it is indeed however just one in terms of to conclude the final answer you must have these steps in mind.
