Lito is a Biostatistician, a professional who uses Statistics to analyze and study data related to Biology. He is one of the consultants of the LGU on putting restrictions because of the rising COVID-19 cases. Every month, the LGU decides whether to heighten or reduce the COVID-19 restrictions. Lito has a daily record of new cases in their place. Another month is about to start so he should give a recommendation on whether to heighten or reduce the restrictions. Restrictions will be heightened if the mean daily new cases in a 30-day period is greater than 100. It is known that the population variance is 1500. He is going to test this at 1% level of significance.(Hint: sample size is 30)
