A random sampleof 319 front-seat occupants involved in head-on collisions in a certain region resulted in 95 people who sustained no injuries. Does this suggest thatthe true (population) proportion of uninjured occupants exceeds .25? Test using a significance level of 0.05.On paper, answer this question using the four-step process. Then take a photo of your work, and upload it to this question.↑ Upload filesSupported file formats: PDF, JPG, GIF, PNG, CSV, RTF, TXT, XPS, ZIP, Word, Excel, Powerpoint, Publisher, Open Office,Video, MATLAB, Quartus, Verilog, C, H, S, V, CPP, Assembly814 of 179 100/2 File Limit1110 11 1248%01:19:31/01:30:0012 13 14 15 16 17&N

An educational psychologist is examining response times to an on-screen stimulus. The researcher believes there might be a weak effect from age, but expects a more pronounced effect for different color contrasts. She decides to examine a black on white (B/W) combination compared to 2 alternatives: red on white (R/W) and yellow on blue (Y/B). Here is the data for response times (in milliseconds): Color Scheme B/W R/W Y/B 10 17 23 26 44 44 22 21 25 22 21 4 16-17 11 32 34 31 24 20 16 20 21 36 8 8 24 37 23 11 39 36 23 17 28 32 36 31 Age 18-19 19 15 45 15 35 36 13 47 23 16 19 31 24 30 25 16 40 16 27 25 42 23 28 35 20-21 21 18 42 27 19 39 39 28 27 18 26 38 Using MS Excel, conduct a 2-way ANOVA with a = 0.05.
