SOLVE STEP BY STEP IN DIGITAL FORMAT, DON'T USE CHATGPT A researcher in criminology is interested in determining whether the average age of offenders in a particular population has changed in recent years. The researcher collects a sample of 100 offenders and calculates that the average age of the sample is 30 years. The standard deviation of the population is known to be 5 years. The researcher wants to test whether there is evidence of a significant change in the average age of offenders, using a significance level of 0.05. Ask: What is the null hypothesis (H0) and alternative hypothesis (H1) in this study? Also, what type of statistical test would be used and what is the process for performing the test with a Z statistic? Perform the necessary calculations and put your conclusions.
