To find the answer using the z - table, find where the row for 1.5 intersects with the column for 0.00; this value is 0.9332. The z - table shows only "less than" probabilities so it gives you exactly what you need for this question. Note: No probability is exactly at one single point, so: P ( Z ≤ 1.5) = P ( Z < 1.5)

WebI think this will be a better approach than using the ratio of probabilities. One final note, if the distributions for the two fertilizers differ, then realistically the probabilities of being within a given range couldn't be exactly identical, and so testing a given range for 'significance' doesn't make a lot of sense to me. WebMar 21, 2024 · To find an odds ratio from a given probability, first express the probability as a fraction (we'll use 5/13 ). Subtract the numerator (5) from the denominator (13) : 13 - 5 = 8 . The answer is the number of unfavorable outcomes. Odds can then be expressed as 5 : 8 - the ratio of favorable to unfavorable outcomes. practitioner education leadetship
