A screening test for high intracranial pressure was proposed many years ago, based on the data in the following observations. This simple and non-invasive test involves observing the retinal vein to see if it is pulsating. Pulsation is normal and so would be considered a negative test result. Pulsation Absent Pulsation Present Total (Positive Test) (Negative Test) High Intracranial Pressure (Condition Present) Normal Intracranial Pressure b. How many false negatives were there?

- The Data The dataset "energy" is a random sample of 56 cases from “Existing Buildings Energy Performance Ordinance Report” from the City of San Francisco Open Data Portal. There are 2,629 cases in the dataset. Citation: SFEBO Help Desk.(Last updated 11/13/2020). Existing Buildings Energy Performance Ordinance Report [data file]. Provided by SF Environment. (Retrieved 11/29/2020). https://data.sfgov.org/Energy-and-Environment/Existing-Buildings-Energy-Performance-Ordinance-Re/j2j3-acqj There are 57 cases. Each case is a building in San Francisco that must be benchmarked using Energy Star Portfolio Manager annually. There are 6 variables: parcel - the parcel number building - the building name postal_code - the postal code year_built - the year the building was built energy_score19 - the ENERGY STAR score for 2019; 1 - 100, where 50 is the national median score, and 100 is best energy performance. energy_score18 - the ENERGY STAR score for 2018 energy.csv download…arrow_forwardComputing the Z-test Statistic The State College is evaluating a new English composition course for freshmen. A random sample of n = 25 freshmen is selected from the State College. All 25 students are placed in the new English composition course during their first semester. One year later, a writing sample is obtained for each student and their writing samples are graded using a standardized evaluation technique. The average score for the sample is M= 76. For the general population of the State College, writing scores form a normal distribution with a mean = 70 and a standard deviation = 20.
