Statistics project Accuplacer scores-total number in sample 425 sample mean 38.1 and sample standard deviation of 14.6 1. What distribution and critical value should you use to calculate margin of error? 2. Perform a hypothisis test to determine if there is sufficent evidence to support the claim that the population mean score of 40 is incorrect, at a 0.1 level of significance. Is the critical value -1.645 or -+1.645
