Question1: It is known the population IO score follows a normal distribution with mean as
u=100, SD as 10. A researcher is interested in studying if the average IQ of students from
statistics courses on average has a higher IQ score than the population IQ score. To test this
hypothesis, the researcher randomly collected a sample of 25 students from statistic class, the
mean IQ score for this sample is x 110. Compete for the hypothesis test at a = 0.05
significant level.
