The observed data for 500 patients is as follows. Category Observed Frequency Surgery 180 Pediatrics 130 Cardiology 155 Neurology 35 Test whether the observed data matches the hospital's report. Use 0.05 level of significance. a) The null and the alternative hypothesis is: H0: P1=0.35, P2= [a], P3=0.30, P4=0.10 H1: Some or all of the actual probabilities [b] from those specified by H0 b) Compute the expected frequencies and the chi-square test statistics. The chi-square test statistics ,
A physicаl therаpist trаcked 12 patients recоvering frоm injury. Each patient’s weekly training hоurs and performance scores on a physical fitness test were recorded over a month. Evaluate the impact of training hours on physical performance improvement. Training Hours (x) 1 4 3 4 5 2 7 8 9 10 7 12 Performance Score (y) 32 60 40 45 80 63 60 67 70 75 80 81 Type your answers i) Compute the correlation coefficient, and round to two decimal places ii) Compute the slope and the y-intercept and write the least squares regression equation for the relationship between X and Y. iii) Interpret the y-intercept in the context of the data. Then, in one sentence, discuss whether interpreting the y-intercept is meaningful and reasonable for this study.
