- Q2) Paired-Samples t Test A research project has been tracking the health and cognitive functions of the elderly population in Arizona. The table below shows the memory test scores from some elderly residents, tested first when they were 70 years old and again when they were 80 years old. The researcher wants to know if there is a significant decline in memory functions from age 70 to age 80 based on this sample. In other words, it is hypothesized that the memory score at age 80 is significantly lower than the memory score at age 70. So the null and alternative hypotheses should be directional. The alpha level was set at α = .01 for a one-tailed hypothesis test. Memory score Subject Age 70 Age 80 1 72 67 2 85 79 3 69 71 4 76 69 5 82 78 6 79 78 7 88 84 8 64 64 9 65 63 10 80 82 a.

Is this an example of a parameter or a statistic? Explain.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.
