Transcribed Image Text:**Question 1:**
It is known the population IQ score follows a normal distribution with a mean \(\mu = 100\) and a standard deviation (SD) of 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 a statistics class. The mean IQ score for this sample is \(\bar{x} = 110\). Conduct the hypothesis test at a significance level of \(\alpha = 0.05\).
