The Cebu Institute of Technology - University Safety and Security Department (SSD) would like to monitor campus security. The SSD is taking a survey of the number of students in a parking lot for 45 minutes in a 24-hour period with the goal of determining when security guards would serve the most students. If X is the number of students in the lot each period, then X is an example of Statistic Continuous variable Discrete Variable Categorical Variable

Battery life is an important issue for many smartphone owners. Public health studies have examined "low-battery anxiety" and acute anxiety called nomophobia that results when a smartphone user's phone battery charge runs low and then dies.† Battery life between charges for the Samsung Galaxy S9 averages 31 hours when the primary use is talk time and 10 hours when the primary use is Internet applications. Because the mean hours for talk time usage is greater than the mean hours for Internet usage, the question was raised as to whether the variance in hours of usage is also greater when the primary use is talk time. Sample data showing battery life between charges for the two applications follows. 1)Test whether the variance is also greater when the primary use is talk time
A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOS) of major corporations. He believes that the mean systolic blood pressure, u, of CEOS of major corporations is different from 132 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOS of major corporations and finds the mean of the sample to be 138 mm Hg and the standard deviation of the sample to be 18 mm Hg. Based on this information, answer the questions below. What are the null hypothesis (H,) and the alternative hypothesis (H,) that should be used for the test? H u is ? H:u is ? In the context of this test, what is a Type I error? A Type I error is ? the hypothesis that u is ? - when, in fact, u is ? Suppose that the researcher decides to reject the null hypothesis.
