- How do you calculate the variable Daily Spiritual Experience Scale (DSES). as a single numerical value to be used in SPSS for data analysis)? What is the potential numerical range and how is it interpreted? What is its scale of measurement? Note: if nominal, numerical is meaningless but necessary for SPSS so you won’t discuss the numbers in your paper.While the world focuses on Covid-19, scientists are working hard to ensure that the Nipah virus doesn't cause the next pandemic. The death rate for Nipah virus is 50.0% . Suppose, 17 patients reportedly infected of this deadly virus are admitted to the central hospital after an outbreak. a. What is the mean number of patients who'll eventually die of the disease? Answer in exact fraction, or rounded to at least 2 decimal places. b. What is the standard deviation in the number of patients who'll die of Nipah infection? Answer in exact fraction, or rounded to at least 2 decimal places. c. What is the probability that the number of death is more than 2 standard deviations away from the mean value? Answer in exact fraction, or rounded to at least 4 decimal places.An electroencephalogram (EEG) is a tracing of brain waves recorded by an electroencephalogranh Neurologists have found that the peak EEG frequency in normal children increases with age in Ph. study (reported in Science, 1982), 287 normal children ranging from 2 to 16 years old were instructed to hold a 65-gram weight in the palm of their outstretched hand for a brief but unspecified time The peak EEG frequency (measured in hertz) was then recorded for each child. The children we grouped according to age, and the average peak frequency for each age group was recorded. The data appear in the accompanying table.

- Using a TI-84 Plus calculator, I need to know the step by step process to calculate these. I don’t need these just written out on paper, but I also need to be shown the every move made into the calculator. Like, ‘STAT’ then ‘TESTS’ then ‘2: T-Test’, and so on.According to the Stanford School of Medicine Blood Center, blood type for Americans is distributed as follows: Type O A B AB Percentage 44% 42% 10% 4% A random sample of 200 Americans is selected and the blood type is recorded for each. The data is summarized in the table below. Type O A B AB Frequency 84 80 19 17 A Chi-square Goodness of Fit Test is conducted to test the hypotheses: Ho: The observed frequencies are consistent with the stated percentages. (The distribution of blood type appears to be correct.) HA: The observed frequencies are inconsistent with the stated percentages. (At least one of the stated percentages is incorrect.) Answer the questions given below.Climate change and CO2 2011 Data collected fromaround the globe show that the earth is getting warmer.The most common theory relates climate change to anincrease in atmospheric levels of carbon dioxide (CO2),a greenhouse gas. The mean annual CO2 concentration inthe atmosphere (parts per million) is measured at the top of Mauna Loa in Hawaii, away from any local contami-nants.

- Study Finds Benefit of Tablet Every Other. Day Is Much Greater Than Expected Ву HAROLD M.SCHMECK Jr. A major nationwide study shows that a single aspirin tablet every other day can sharply reduce a man's risk of heart auack and death from heart at- tack. The lifesaving effects were so dra- matic that the study was halted in mid- December so that the results could be reported as soon as possible to the par- |ticipants and to the medical profession in general. The magnitude of the beneficial ef- fect was far greater than expected, Dr. Charles H. Hennekens of Harvard, principal investigator in the research, said in a telephone interview. The risk of myocardial infarction, the technical name for heart attack, was cut aimosi in half. 'Extreme Beneficial Effect A special report said the results showed "a statistically extreme benefi- ciał effect" from the use of aspirin. The report is to be published Thursday in The New England Journal of Medicine. In recent years smaller studies have…What is cognitive age? How is it measured?What is Chi-square test? Explain the benefits.
