It is known from the records of the City Schools that the standard deviation
of Algebra scores is 6.0. A sample of 200 students from the system was
taken and was found out that the sample mean score is 75. Previous tests
showed the population mean to be 70. Is it safe to conclude that the
sample is significantly different from the population? Use α= 0.05.
